Sound with Delphi 1

[Roderich]

hi there,

does anybody know how to play simple tone given by frequency via Sound card ?
I found some Delphi assembler code to play a sound via PC speaker, but PC speaker quality is quite poor :-/

Do I have to use DirectX or what ?

Any hints or tips ?

best Regards
Rod

heres what it can do
* A choice of five waveforms.
* Amplitude Modulation to allow the creation of complex waveforms.
* Full AHDSR envelope shaping to alter the dynamics of selected waveform.
* Frequency range of 20Hz to 20kHz.
* Simple method of assigning musical note values.
* Tone duration from 10mS to 30 seconds.
* Choice of sampling rate and resolution.
* Independent left and right volume control.
* Simple control of audio looping.
