[HELP] represent PC speaker beep with audio file (self.programming)

submitted 1 year ago by zolax to c/programming

for a while, I have been using hardware through Linux that uses the beep from the PC speaker. I'm actually really used to it, so when I switched to using hardware with an unusably loud (volume can't be changed) volume (and also different frequency), I started looking into "exporting" the original beep to an audio file that could be played at different volumes and for other purposes.

looking through the internet, however, I haven't found any attempts to represent any actual PC speaker beep in an audio file, so I'm asking you guys if you know how to do so. presumably, the beep is just a short, simple waveform at a certain frequency, but I am not sure what that waveform is, or what the easiest way to do so is.

If you have the hardware, you could record the beep by removing the PC speaker and wiring those terminals directly into an audio recorder or the mic jack on another computer. That way you'd have the exact sound you want.

Understandably not everyone can do this, so an alternative could be to record the sound with a normal microphone and then use software to determine the frequency of the beep so you can recreate it in Audacity or something. I don't know the names of any off by heart, but I'm sure there will be some free ones online.

not really able to remove the PC speaker, but in line with @atheken's and your comment, I'll probably generate the tone in Audacity and figure out the frequency with a recording
