Save your recordings as .WAV files. Don't use MP3 format and
don't convert the recordings into MP3 recordings. Leave the

Let me stress the importance of this. MP3 is a lossy format, designed only
to make something that sounds like the original signal did to the human
ear. It is not intended for digitally modulated signals that are to be
decoded by a modem!
Although the BPSK1000 format has actually been decoded from an
MP3-compressed copy, this came as quite a surprise to me - it's certainly
not something to rely on!
A *lossless* compression scheme like FLAC, Shorten or Apple Lossless would
be fine, if you have one. But if you're not sure, just keep the original
.wav files. Thanks!
