Re: CD player
I love my EMU external mini DAC.

If you go this route, note that the general run-of-the-mill soundcard that

the brand or size/shape) you will need to either upgrade the internal
soundcard or use an external soundcard as your audio source. There are some
nice USB-soundcards that provide very clean audio for around the $100-mark.
If your source is going to be CD I'd probably steer clear of the $40 models -
again you'd probably get the best bang for the buck from a PC with an

Cheap players may have more mains hum, in my experience,

If you are controlling the experiment with a computer, you
may find it a lot simpler to generate stimuli with the
sound card. You can use my Daqarta for Windows software
(free for signal generation uses) to generate signals in
real-time. It can produce a broad range of waveforms
(inlcuding arbitrary ones you define) and modulation types,
and you can create extremely complex signals by using
signals as modulators for other signals.
Let me know if you want advice about applying Daqarta to
your particular needs.
