Help: Tape Restore Live!: Digitizing tapes: Do's and don'ts
[October 3 2006 - still needs to be written]
Don't use MP3s, or at least let them go to 20 kHz.
Better: Use .WAV files or lossless FLAC compression if you want to compress.
Keep the original raw recordings, not the ones processed by this plugin - newer versions might be better, and calibration can be changed during playback.
