That is *huge*. What compression are these files using?
If using an efficient form osf compression, the files will
become much larger still, in memory.
Not really. A typical MP3 of a song is about 4 or 5 megs at 192kbps
(exact size dependent on song length of course). With MP3 you can expect
about a 5:1 compression ratio so the original WAV is approximately 50
megabytes. He is working with files then about 4 times the size of a
typical song (~4 minutes long). He may very well be working with a 20
minute file with average bitrate or a shorter file with high bitrate.
WAV is not usually compressed and contains data in PCM format which
explains why files can be, as you say, *huge*. In reality, they aren't
huge for that format because they aren't compressed. But are they huge
compared to their compressed MP3 cousin? You could make that argument.
