To start the conversation again, simply ask a new question. Listeners don’t need all the data on a CD, since much of it is imperceptible to the human ear. Thread starter tops; Start date Jan 14, 2002; ... or in a noisy environment, but in a quiet room and through a good set of speakers or headphones 128 doesn't sound as good as 256 or 320(snares and cymbols don't sound right to me). I can easily hear the difference. hhgttg27, Mar 25, 2016 8:57 AM in response to ehlersgrub, Mar 25, 2016 9:06 AM in response to ehlersgrub, Mar 25, 2016 9:10 AM in response to hhgttg27, Mar 25, 2016 9:18 AM in response to ehlersgrub. For … The higher the Kbps of an audio file, the more space it will … null-OTHER, (128 kbps AAC is generally better than 128 kbps MP3.) Probably not so much difference with ear buds but what about when I play through a higher quality in home sound system? The same holds true even when the bit-rate is reduced to 192 Kbps. 192 kbps sounds better regardless of the encoding quality. Many similar tests have proven that most humans have trouble detecting any change in audio quality above 160->192 Kbps or in mp3s. I constructed a playlist in iTunes so it would fit on my iPod nano. 128 kbps quality vs 256 If you've been importing CDs at 256, 128 won't be that different. Sound compression takes advantage of this fact by removing all that extra information. Similarly, you’re not going to hear the difference in a car, where tonal quality is already murky, but you might if you’re wearing your noise-canceling headphones. I am wondering if I should go back and redo the whole process at 256 kbps. Hagámoslo más gráfico con esta tabla: 4 Kbps es el mínimo del estándar 8 Kbps es la calidad telefónica 32 Kbps corresponde a la calidad de radio AM My intention was not to further compress the music from my iTunes playlist to get more on the iPod. mp3 CBR@256.1 (Audition 1.5) - MPEG-1 Layer 3 CBR, 256.1 kbit/s FBR CODER: MP3/mp3PRO(R) Encoder for Adobe Audition 1.5 - Codec: Current - Best Quality - Allow Mid-Side Joint Stereo: No - Allow Intensity Joint Stereo: No - Allow Narrowing of Stereo Image: No - 44100 Hz Joint Stereo DECODER: MAD 0.15.2b Looks like no one’s replied in a while. User profile for user: All these variations make it difficult to say for certain whether 256 kbps will sound noticeably better than 192, or 160, or 128 kbps. This is something of a "how long is a piece of string" question ... one of the variables involved is the type of music you listen to: a reduced bitrate may have obviously detrimental effects - even on standard earbuds - when applied to recordings with a wide dynamic range, particularly classical or jazz. Roughly speaking, a higher bit rate indicates higher quality, so a 128-kbps MP3 is twice the quality of a 64-kbps … I just synced that playlist on my iPod and the file size was about half of that on the computer. Any comments or thoughts would be appreciated. It all depends on your hearing. (Going from 64 kbps to 128 kbps adds more important data than going from 128 kbps to 192 kbps.) I just synced that playlist on my iPod and the file size was about half of that on the computer. Because I'm considering doing the unthinkable - changing the bit rate of most of my songs to 128 kbps, and possibly degrading the sound quality by a … Only when the bit-rate is 128 Kbps or lower, does the difference starts seeming obvious. 160 Kbps or higher will produce CD-quality sound. But a listener’s ability to distinguish sound quality depends on many factors, like age, hearing ability, and attentiveness, not to mention the style of music and where one listens to it. My question is how good is the resulting quality of the 128 kbps songs on my iPod? Is the difference as big as you expected? As a result, about 90 percent of an audio CD’s original data gets thrown away in the MP3 compression process. CD sound is 1411 kbps. Scrape 'em off and reimport at the lower bit rate, and be happy you're using half the space. iTunes usually sells their music in 128 AAC format, and some of them in 256 AAC, I can't really tell a difference in it, but then again, I am soon to upgrade my headphones to either Ety ER-4P's or SF5 Pro's. 256 Kbps — which fun fact is also Uganda’s country code — is the speed that your internet will drop to once you have climaxed your data cap. I can most certainly tell the quality difference. A 5 min. That said, each extra bit you add when expanding a compressed file will be less essential than the last. I certainly don't see any benefit to me of downsampling as I sync to an iPod (my default device is a 16GB nano 7G, so at 256k/320k I still get around 100 hours of music on there). All the songs were converted from CD's to iTunes. Mar 25, 2016 9:18 AM in response to ehlersgrub For example, music with delicate timbres—a string quartet, say—might sound noticeably choppy at lower bitrates, whereas compressing an AC/DC song might not be so bad. If you compress at 128 kbps with the encoding setting set to "high" the difference between 128 and 192 kbps will not be that easy to hear. The luxury tracks will cost 30 cents more than the standard downloads. I constructed a playlist in iTunes so it would fit on my iPod nano. With the growing trend of ipods and such, mp3’s and other compressed audio formats are taking over the need to play music directly from a cd. Any comments or thoughts would be appreciated. But that only accounts for a small amount of savings. Explainer thanks Peter Cariani of Harvard Medical School, William Hartmann of Michigan State University, and Adrian Houtsma of the U.S. Army Aeromedical Research Laboratory. Is it worth the extra memory to up the quality from 192 to 256. The thrown-out data are usually frequencies which aren't (saw/heard/became aware of) as much by the human ear. All the songs were converted from CD's to iTunes. I just synced that playlist on my iPod and the file size was about half of that on the computer. All contents © 2021 The Slate Group LLC. (This type of compression is called “lossy,” as opposed to “lossless.” You lose data during “lossy” compression, whereas “lossless”—think ZIP files—allows you to reassemble the whole thing later.) It was an accident because the bit transfer was set at 128 kbps. If you change your mind, you can simply resync your iPod with that setting on 128, 192, 256, or turned off altogether. I just synced that playlist on my iPod and the file size was about half of that on the computer. (The bitrate measures how much digital information gets transmitted every second. The sound quality of a file at any bitrate also depends on the compression program or “codec” used to create it; some work better than others. The lower the Kbps, the more data the encoder will eliminate when compressing an audio file; the range for bit rates is from 96 to 320 Kbps. Ask the Explainer. A well-designed codec will only get rid of stuff you wouldn’t notice in the original record; that’s why the codec you use to compress a file can be more important than its bitrate. Mar 25, 2016 9:06 AM in response to ehlersgrub That final “s” in kbps stands for “seconds” – so there are 128,000 bits of data in every second of a 128 kbps MP3 file. The options are usually "fast", "medium", "high". AAC is known to have better quality than MP3 at low bit rates like 128kbps, but once you get into higher bitrates like 256kbps and above, the differences become pretty much indistinguishable and most people can't reliably tell the difference between them … In response to ehlersgrub. So, as you compare higher and higher bitrates, sound quality becomes harder to distinguish—the musical equivalent of diminishing returns. accer pc, Mar 25, 2016 8:57 AM in response to ehlersgrub track at 128 kbps is about 4.6 MB and at 256 it's about 9.2 MB. So what does 128k (or 128 kBPS) actually mean? For starters, codecs throw out frequencies outside the range of human hearing—roughly 20Hz to 20,000 Hz. Codecs like MP3 and iTunes’ AAC chop up music from a CD into little time frames and, for each one, determine which frequencies to keep and which to discard. You could import music files in MP3 (16 to 320 Kbps), AAC (8 to 256 Kbps), MP3 VBR, FLAC, WAV, Ogg-Vorbis, etc., organize and manage your music library, as well as listen to separate files, since the application includes a music player of its own. Is 128 kbps wireless service frustratingly slow (to load pages due to pics and ads on every new page) or okay for my wireless usage purposes? Having said that, across a reasonable wide range of music within my library I find that 256k AAC / 320k MP3 is acceptable across several different platforms: iPod with mid-range Sennheiser earbuds (not ridiculously expensive but considerably better than those supplied by Apple), PCs with desktop speakers, hi-fi system with Bluetooth audio adapter (though in the last case I'll still listen to CDs by preference). Q: Question: Q: 128 kbps quality vs 256. To save even more space, the codecs also scrap frequencies that would be audible on their own but become virtually imperceptible in the presence of other sounds, like a booming bass. Whats sound is better when ripping a cd? In this case, theoretically, Apple Music’s 256 kbps bitrate shouldn’t sound as good as the 320 kbps offered by its rival services. But I’ve never noticed the difference in quality, especially when dealing with 192 kbps mp3’s. As far as I know you will hardly hear the difference and if you happen to manage AAC will probably do better. And you'll never see this message again. Bit rates range from 96 to 320 kilobits per second (Kbps). If you value our work, please disable your ad blocker. When you convert it to mp3, some of the sound data is thrown out to make the filesize smaller. A quick web search will show that even "audiophiles" really can't discern the difference. My question is how good is the resulting quality of the 128 kbps songs on my iPod? I guess you are saying I might experience some loss especially with better quality ear buds or when playing on a better quality sound system via blue tooth. For years, I’ve known that yeah, you lose quality when you compress a CD WAV file into a compressed mp3 file. In digital multimedia, MP3 files included, the bitrate represents the amount of information, or data, that is stored per second/minute/whatever of a recording. This site contains user submitted content, comments and opinions and is for informational purposes only. In general, the more bits, the better. More 128 Kbps quality is typically considered radio quality, and a bit rate of 160 or higher is equivalent to CD sound quality. OK. Got that. The principle works the same as video bitrates. All postings and use of the content on this site are subject to the. We suggest that you start from 128 Kbps at least. Thats a 64 MB difference, which is alot. Also note that the "shrink-and-sync" capability creates compressed files for the iPod, but does not alter the original file that is in your library. All rights reserved. OK. Got that. Find and join some awesome servers listed here! So a 256 kbps MP3 or AAC file is better than a 128 kbps file. 128 vs 192 kbps. (To compare different bitrates for yourself, click here or here.). Slate is published by The Slate Group, a Graham Holdings Company. Higher audio bitrate is one of the perks of server boosting: at level 3, the bitrate can be set to 384 kbps; at level 2, 256 and at level 1, 128. However, if you're planning to re-encode a bunch of MP3s, you're going to degrade the sound quality, probably by a lot. CDs operate at 1,411 kbps, more than 10 times the rate of MP3s.) But I'd doubt if you could tell any difference with a voice recording. Will people be able to hear the difference? I clearly hear the difference on my computer between 128 kbps and 192/256 kbps. … To start the conversation again, simply ask a new question. Record label EMI and Apple announced Monday that iTunes will soon offer premium music files, which come without copy protection and have a bitrate of 256 kbps instead of the usual 128 kbps. You can tell with a music track that's there's slightly lower quality with 128 kbps compared with 256 if you play it on a high quality stereo system. But all else being equal, a song’s bitrate provides a reasonable indicator for sound quality. I constructed a playlist in iTunes so it would fit on my iPod nano. I think theres a huge difference between 256kbps and 320kbps if you a/b the audio. or should i go for 192 and save the extra memory. Probably not. After some research I found that all the CD's had been converted at 256 kbps but when I synced the iPod the converter bit rate was set at 128 kbps(default setting in iPod Summary Options) which explains why the resulting file size on my iPod was about half the file size of my iTunes playlist. I'd go as far as to say there's noticeable differences down the entire range of kbps settings for mp3. When I am downloading stuff I always prefer (at least) 192 kbps but if I can get higher I will always do that. The music on iTunes is 256 kilobits per second. Download the MP3 audio version of this story here, or sign up for The Explainer’s free daily podcast on iTunes. Windows 10, 128 has a clear "tinny" quality that disappears as the bit rate goes up. BD231 Lifer. Which Kbps bit rate mp3 format is the best quality? Also, if you want to compare high-resolution files, make sure you open Audio MIDI Setup (in the /Applications/Utilities folder), and set the sample rate to the highest possible setting. F or preserving as much sound quality as possible @128 kbit/s SoundExpert recommends compressing music with these coders:. (Going from 64 kbps to 128 kbps adds more important data than going from 128 kbps to 192 kbps.) After some research I found that all the CD's had been converted at 256 kbps but when I synced the iPod the converter bit rate was set at 128 kbps(default setting in iPod Summary Options) which explains why the resulting file size on my iPod was about half the file size of my iTunes playlist. In response to hhgttg27. The only difference is file size. Dicho nivel de compresión puede llegar hasta 320 kbps, la calidad máxima, en la cual la reducción del tamaño del archivo es de cerca de 25%, pasando antes por 192 kbps, 256 kbps. The "kbps" number in an MP3's metadata, or kilobits per second, indicates the bit rate, or level of compression, that the MP3 encoder used to create the MP3. Heck, I cant hear the difference between old 128 kbps mp3 and CD, ats all the same. Contemporary popular music, or "remasters" of older recordings that suffer from the "loudness war" where recordings are compressed to sound as loud as possible may suffer less. Got a question about today’s news? Slate relies on advertising to support our journalism. X = A (320 kbps) ... With this simple test you'll be able to find out whether you can hear the difference between a low quality song and a two-and-a-half times larger high fidelity mp3 file. On my home theater I can hear a huge difference between FLAC and 192 kbps MP3. This is especially true for users who are subscribed to “unlimited” internet bundles. Step 3 Which clip is X? 192 KBPS or 256 KBPS? Unless you have a specific reason to downsample as you sync I would clear that setting and update your iPod again. In any case, doubling the bitrate from 128 kbps  to 256 kbps  won’t make music sound twice as good, because the smaller file already has the most important information. With a few exceptions I would normally be able to detect a lower bit rate recording (though without doing proper double-blind testing there's always an element of subjectivity). 3. But there’s more to it than just bitrate. For instance, at 256 Kbps, audio encoded in both MP3 as well as AAC will sound the same. Less, User profile for user: ehlersgrub. It's just that once you get to 160kbps, any sound quality should be tolerable. Votes: 7 14.9% Amazon 256 kbps mp3 is fine, anyone who needs more is a buffer. Apple uses the AAC format for its tracks, which tends to be much better than the normal MP3 format because of the way in which it’s encoded. Mar 25, 2016 9:10 AM in response to hhgttg27 AAC family encoders both LC and HE profiles from iTunes, Nero and Winamp; MPC; Disclaimer: The above recommendations relate exclusively to perceived audio quality of encoders but not their popularity, compatibility … In response to ehlersgrub. That is, the higher the number, the better the sound quality, the more encoding power needed. The lower the Kbps, the more data the encoder will eliminate when compressing an audio file; the range for bit rates is from 96 to 320 Kbps. Encoders 128 kbit/s. All the songs were converted from CD's to iTunes. Apple may provide or recommend responses as a possible solution based on the information provided; every potential issue may involve several factors not detailed in the conversations captured in an electronic forum and Apple can therefore provide no guarantee as to the efficacy of any proposed solutions on the community forums. Question: Studies (PDF) have found that as long as you’re using high-quality encoding software, music compressed to a bitrate of 128 kbps or more is “transparent”—in other words, most listeners can’t distinguish it from CD quality. clip B (128 kbps) Step 2 Listen to clip X. clip X (128 or 320 kbps?) Probably not so much difference with ear buds but what about when I play through a higher quality in home sound system? I notice a huge difference from 64 kbps to 128 kbps, but is it the same from a 192 to 256? In response to ehlersgrub. Question: Q: 128 kbps quality vs 256. For Mobile and Tablets Videos The higher the bit rate is, the better quality is of an audio file. Some tracks sound a little cleaner in FLAC than 320 kbps MP3 but the quality gap is much less obvious, however i upload everything to Google Play Music for streaming in my car since 320 kbps mp3 is fine given how much extra noise there is in a car vs sound treated room. With iTunes, you can rip in Apple Lossless format, then have iTunes convert your music files during the sync process to 128, 192 or 256 kbps. My question is, if with my SF3's I can't tell the difference in the quality… I never pay for computerfiles/ITunes or whatever so all the stuff mentioned in this post has to do with getting stuff for free. All these 5 tools could help you easily convert MP3 files from 128 kbps to 320 kbps in bitrate. Apple disclaims any and all liability for the acts, omissions and conduct of any third parties in connection with or related to your use of the site. You can also try 320 Kbps for maximum audio output. All the songs were converted from CD's to iTunes. By joining Slate Plus you support our work and get exclusive content.
