I'm working on web application which will be using timidity++ to converting midi file into wav file. I know that it will not work without sound card, so I must have server with it. My question is: Is the used sound card will impact to the speed of generating wav files? And if the answer to my question is yes, what should I pay attention when I buy sound card. What sound cards what can you recomend?
The sound card should definitely not impact the speed of synthesis, especially if you are doing it offline. In fact, software such as MrsWatson can use a VST instrument plugin to synthesize MIDI events to an audio file and do not require any sound hardware at all.
