about the audio record quality

helijia2001 · Jul 27, 2005, 08:18 AM

The quality is not good when i record music using recorder(written myself)by setting the record line as "wave out mix" or "wave" or "Stereo [color=#cc0033]Mix"[/color]in recording control. Why?
Can i modify the quality in my program using mixer-xxx API?
Anybody can help me?thanks!!!!!

what are you recording with? microphone?

helijia2001 · Jul 27, 2005, 11:26 AM

No ,i record a mix of sound from multiple sources.For example ,when i playing music ,i use the "wave out mix" or "wave" or "Stereo [color=#cc0033]Mix" line(they are the same line in sound card) record the sound.[/color]

[color=#cc0033]My recording is to any media player,such as mediaplay er,winmap,MTV player and so on.[/color]

if you use stereo mix as an input, mute the microphone - that should help increase quality

In my computer the wave out mix has insteaded of stereo mix,there is no sterero mix input in my computer,i used wave out mix input as you said ,but have no effect.
