Information in this article applies broadly to all devices capable of playing digital music files. Sound quality will vary depending on the device speakers. Likewise, the MP3 format also works on any operating system.
You should have no problem playing either file type on any device. To examine the differences between the formats, let's compare the song Wild Sage by The Mountain Goats encoded in each format at three different speeds: Kbps, Kbps, and Kbps.
The higher the Kbps, the bigger the file, but the better the quality. The MP3 version is 1. These versions sound a bit muddied compared to the Kbps versions. The MP3 is almost 1MB smaller. The AAC file is a bit clearer and brighter than the MP3, which suffers from slight muddiness and slurring some sounds together. The file sizes are almost exactly the same. While there are differences in the sound waves of the files, they sound roughly equivalent to the ear.
Though there may be a bit more detail in the Kbps MP3, it's difficult for an untrained ear to discern. The only place you're likely to hear a difference is in the low-end Kbps encodings, which aren't recommended. Most audiophiles who place great value on the best possible sound quality tend to avoid MP3, AAC, and other digital audio formats because these formats use compression to create smaller files.
The trade-off is that the highest and lowest ends of the sound range are lost. Most average listeners don't notice the loss, but it can be a deal-breaker for audio aficionados. Actively scan device characteristics for identification. The file may be smaller if you use VBR. I found the error was because I was only changing the cache location, not the ultimate mp3 file destination and the last-used location was on a drive that was not connected.
How can I tell what bit rate any one particular song was compressed to? Started with then changed to Lossless. Where can I find that info for a song? Thank you, Wayne. All my music so far is at iTunes Plus , but I stopped midway through ripping all my Cds to research this further.
I think I may start over and do them all at Am I understanding this correctly? I now have all together a Gig library. Here is my question: How would you recommend I proceed to revamp my library?
Can i have 2 libraries for a while and then switch? Also thank you so much for a wonderful article written in a way that ordinary knowledgeable people understand. VBR came along and really helped by providing more bits for the complicated sections and simply upping to kbs VBR became very hard to tell the difference.
To be safe kbs should be fine but Apple had to goto kbps for marketing reasons. Thanks for the great info. I was just wondering, I purchased a lot of songs from iTunes. And I just noticed they were mostly in kbps. Is there a way to have them re-downloaded at kbps or the best quality? Without re purchasing them again?
The maximum you can buy on the Apple store is kbps AAC. You may try use Avdshare Audio Converter to convert MP3 bitrate step by step guide and also help to change other audio format bitrate or video format bitrate.
Is one of them better than the other or something like that? Do you know which format is best to use with high quality on a laptop to play the music files on the big stereo speakers?
Any mac with iTunes 2. Lossless is always better than compressed. Only compress them if you need the disk space. Foe example if you are putting them in an ipod and you want more songs to fit it makes sense to compress them.
AAC 3. Lossless is always best audio quality. I use Virtual DJ and a Mac. Advice needed! Please and Thank you! MP3 and other compressed formats definitely degrade the sound. Select for importing audiobooks , not music.
Set custom settings for greater control over the quality and size of imported files when importing using AIFF Encoder encoding format. Sample Size: The number of bits used to store each sample taken as the music is encoded. The higher the sample size, the better the quality and the larger the file size. Set custom settings for greater control over the quality and size of imported files when importing using MP3 Encoder encoding format.
Stereo Mode: In Normal mode, your MP3 files contain one track for the right stereo channel and one track for the left. In many cases, the two channels contain related information. At bit rates of kbps and below, this can improve the sound quality of your converted audio.
Smart Encoding Adjustments: Select to have iTunes analyze your encoding settings and music source. Filter Frequencies Below 10 Hz: Select to filter inaudible frequencies, which results in smaller, more efficient files without perceptible loss of quality. Set custom settings for greater control over the quality and size of imported files when importing using WAV Encoder encoding format.
Choose import options Your choices affect the audio quality and size of the song file the higher the quality, the larger the file size. Choose an encoding format from the Import Using pop-up menu. If you chose MP3 Encoder, you can choose one of the following: Good Quality: Choose to fit more songs on a portable MP3 player with limited storage capacity.
Custom: Choose for greater control over the file size and sound quality.
