Re: CD player

If you go this route, note that the general run-of-the-mill soundcard that comes as part of a PC-bundle or laptop is not a very high- quality piece of kit. In my experience, if you need good quality sound from a PC (no matter 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 external USB-soundcard.

Dear List,

We have a need for a CD player to play audio files (6
kHz BW) for an OAE experiment. Is there a particular
kind of player I should look for? how would a $40 home
CD player, for instance, compare with fancy stuff you
can get for hundreds of $$? Stimuli will be steady-state
and modulated, simple noise and more complex..

Cheap players may have more mains hum, in my experience,
but it's hard to make a general rule based on selling

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.

Best regards,
