Audio digitization workflow:
- Prepare the analog original (use appropriate techniques, such as tone callibration, restoration, baking, etc.)
- Route the signal through a mixing board AUX send/return or Channel insert/return into a compressor/limiter - only for "soft" tapes with significant amplitude variability.
- Send the signal to a stand-alone A/D converter
- Send the digital audio data stream to a PCI capture card via AES/EBU or S/PDIF
- Make 2 CD-ROM (ISO standard) copies of the master file
- Initiate script to process and move the "working" audio files into the digital repository.
The batch script may inlude:
- downsampling to 22,050 Hz
- changing the resolution to 16 bit with dither and noise shaping
- 2:1 compression at -18 dB
- noise reduction
- RealAudio encoding
