In fact there’s a lot of debate around whether there is a perceivable difference between high bitrate MP3s and WAV files (try this test to see if you can tell the difference). But while this may sound like a big price to pay for a smaller file size, the difference between an uncompressed file and a high bitrate AAC is going to go unnoticed by all but the most picky of audiophiles. With lossy formats information is removed from the file to reduce the file size, ultimately reducing the audio quality of the file. The way in which this is done depends on whether the compressed audio file is a lossy or lossless format (which essentially do what they say on the tin). The big advantage that compressed audio files have over their uncompressed counterpart is the file size. This is where compressed file formats come in. Examples of uncompressed audio files include WAV and AIFF (essentially Apple’s version of WAV).īut while having your audio in its highest quality form is no doubt a good thing, there’s one major downside to uncompressed file formats – they’re large, and sometimes that’s just not practical. This means that you’re getting all of the audio as it should sound making it the highest quality you can achieve with digital audio. Uncompressed file formats are essentially the entire raw audio file with no compression applied (not to be confused with the audio processing effect!). We can split audio files (or codecs) into two different categories – compressed and uncompressed – with there being some key differences between the two making them suited for different purposes. While this in itself may seem overwhelming, plenty of DAWs have even more options than this so it’s essential solid understanding of audio file formats so you’re exporting your track in the right format when the time comes. Most DAWs will present you with a myriad of different options when it comes to exporting the track – just take a look at GarageBand’s export options: WAV, AIFF, Apple Lossless or AAC (complete with a selection of four different bit rates ranging from 64kbps to 256kbps). However, the process of bouncing your music down to an audio file is not quite as straightforward as it may seem. So you’ve finally finished your track and you’re ready to share your masterpiece with the world.
