This scales back the sound playback level, in case your audio algorithm blows up.

| Description |
This is a simple function to prevent massive clipping and possible hearing damage in case the audio algorithm you were working on happens to be unstable or has too much gain.
This is not a limiter; it just scales back the entire signal if necessary to ensure that the maximum peak value is no more than +/-1.0. If the peak input level exceeded 1.0, safesnd() displays the amount of playback level reduction in dB. There's nothing magic here; it's just a handy utility function.
Also, note that it is generally not a good idea to debug your audio algorithms using headphones! |
