There is much that could be said on this subject, but most of it -would be irrelevant here. The short version is that for most games 22050 Hz is -fine, but in some cases 44100 Hz is preferable. On extremely low-end systems -you may want to use 11025 Hz, but it's unlikely that you have to worry about -that. - -To elaborate, most of the sounds ScummVM has to play were sampled at either -22050 Hz or 11025 Hz. Using a higher sample rate will not magically improve the -quality of these sounds. Hence, 22050 Hz is fine. - -Some games use CD audio. If you use compressed files for this, they are -probably sampled at 44100 Hz, so for these games that may be a better choice of -sample rate. - -When using the Adlib, FM Towns, PC Speaker or IBM PCjr music drivers, ScummVM -is responsible for generating the samples. Usually 22050 Hz will be plenty for -these, but there is at least one piece of Adlib music in Beneath a Steel Sky -that will sound a lot better at 44100 Hz. - -Using frequencies in between is not recommended. For one thing, your sound card -may not support it. In theory, ScummVM should fall back on a sensible frequency -in that case, but don't count on it. More importantly, ScummVM has to resample -all sounds to its output frequency. This is much easier to do well if the -output frequency is a multiple of the original frequency. - - -%%% Local Variables: -%%% mode: latex -%%% TeX-master: "readme.tex" -%%% End: |
