For digitization, best to use Simon (Audio Lab, 2101B) for PC, or Faust for Mac (Computational Lab, 2101D). These computers are in isolated rooms so that you can listen over speakers without bothering others. Quimby is also set up as an audio station.
Direct input of digital recordings from DAT
- To use Simon, see the instructions in the Audio Lab. Simon has PCQuirer/Pitchworks, Multispeech, Praat, Audacity, and other audio editors that you can use to capture speech from the analog cassette player.
Simon's and Quimby's sound card allows digital capture as well as analog-to-digital capture. Follow the instructions in the Audio Lab for setting this up. You will need to use Audacity to acquire the digital speech, but if you save it in .wav files it can be analyzed in any program.

2. The analog signal from the tape deck will be output to Channel 1
of CSL. First, adjust "output" level by using the "output" knob on
the front side of the tape deck. Second, adjust "input" level
by moving the top left knob on the CSL box, which is labeled as "Input
Ch1". Adjusting both input and output levels is important to maximize
Signal-to-Noise ratio (i.e. the ratio of signal amplitude to quantized noise
amplitude). In both cases, try to maximize level but not to exceed limit.
Signal overload will be indicated by red color of the Channel 1 input indicator
of the CSL box.
3. CSL has only a red cursor. Stay in the A window. Place the cursor and click the mouse to mark the beginning of the portion of the waveform that you want to save. Move the cursor and mark the end of the portion in the same manner.
4. Type "s". All digitized speech files will be automatically suffixed with "NSP". You will see the SAVE SAMPLED DATA box. Type a name of the speech file. Keep the prefix "d:\", which indicates the zip drive (d-drive). Click "OK".
6. Repeat the same process for the digitization of
