The usual bitstream encoding is the Linear Pulse Code Modulation (LPCM) format. It is the main format used on Windows systems for raw and typically uncompressed audio. It is an application of the RIFF bitstream format method for storing data in “chunks”, and thus is also close to the 8SVX and the AIFF format used on Amiga and Macintosh computers, respectively. WAV Encoder: Waveform Audio File Format, (rarely also named Audio for Windows) is a Microsoft and IBM audio file format standard for storing an audio bitstream on PCs. MP3 Encoder: The use in MP3 of a lossy compression algorithm is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio for most listeners. It is not a variant of AAC, but uses linear prediction similar to other lossless codecs such as FLAC and Shorten.

In addition to audio data, AIFF file can include loop point data and the musical note of a sample, for use by hardware samplers and musical applications.Īpple Lossless Encoder: Apple Lossless data is stored within an MP4 container with the filename extension. Like any non-compressed, lossless format, it uses much more disk space than MP3 - about 10MB for one minute of stereo audio at a sample rate of 44.1kHz and a sample size of 16 bits. Standard AIFF file is a leading format (along with SDII and WAV) used by professional-level audio and video applications, and unlike the better-known lossy MP3 format, it is non-compressed (which aids rapid streaming of multiple audio files from disk to the application), and lossless. AAC provides audio encoding that compresses much more efficiently than older formats, such as MP3, yet delivers quality rivaling that of uncompressed CD audio.ĪIFF Encoder: Audio Interchange File Format ( AIFF file) The audio data in a standard AIFF file is uncompressed pulse-code modulation (PCM). Here are the audio codecs available on iTunes:ĪAC Encoder: Advanced Audio Coding (AAC) is at the core of the MPEG-4, 3GPP and 3GPP2 specifications and is the audio codec of choice for Internet, wireless and digital broadcast arenas. You can always export to a mp3/mp4 format latter. I advise that you do the following: import all of your CDs using the highest quality AIFF onto an external drive. Once you convert to a mp3, then there is no way to convert it to a higher audio quality and you will be stuck with low quality audio. If you decide to go with mp3, then you can be assured that your files will be smaller but they will also be of lower audio quality. The downside of m4a is that the files are larger.

m4a provides the highest quality audio: at the iTunes Plus setting you get 256 kbps for stereo at 44.1kHz.

There is a lot of confusion with these two file extensions, but the bottom line is that they are both the same. This being the case, then there is only one choice for me.mp4 or m4a. I approach my conversion with one thing in mind, I want the highest audio quality possible. With each codec comes both some good and bad. It is easy to transfer music from a CD to anywhere you want, but before you begin importing your audio you need to make a decision as to what audio codec you want to use.mp3, wma, mp4, m4a, etc.
