audio cue

1
dear psychtoolbox users,

I may use an audio cue in the visual experiment. In C/DOS, I can
realize it via PC speaker (at certain frequence and certain duration).
Now in Psychtoolbox l can only do with a prepared audiofile and play
it via soundcard. It would be inconvenient and the sound from
soundcard was always not loud enough. Is it possible to make audio cue
in an easier way? It can be very simple sound: diiii...or daaaa...
etc.

There are actually a lot of ways to play sound, at least in matlab 7
under windows:

PlayBeep.m: % [theSound,samplingRate] =
PlayBeep(freq,durationMS,[samplingRate],[DONTPLAY])
SndPlay.m: % err = SndPlay([sound],[rate])
SoundPlay.m: % SoundPlay(data,[samplerate])
SndTest alternately plays the same sound (someone saying "why")
BEEP Produce beep sound.
SOUNDVIEW View and play sound with replay button
AUREAD Read NeXT/SUN (".au") sound file.
AUWRITE Write NeXT/SUN (".au") sound file.
SOUND Play vector as sound.
SOUNDSC Autoscale and play vector as sound.
WAVPLAY Play sound using Windows audio output device.
WAVREAD Read Microsoft WAVE (".wav") sound file.
WAVRECORD Record sound using Windows audio input device.
WAVWRITE Write Microsoft WAVE (".wav") sound file.
XPSOUND Demonstrate MATLAB's sound capability.
NNSOUND Turn Neural Network Design sounds on and off.
PLAYSND Implementation for SOUND


looks like playbeep is the place to start for your needs.

Thanks.
Playbeep works well.
Though it is still from soundcard rather than PC speaker, it is loud enough.
I tried all others before except for this one and XPSOUND NNSOUND.
