View Full Version : Kinoma audio volume
04-25-2003, 07:03 PM
Converted a short avi video using Kinoma Producer and setting the audio boost to high. When using headphones the volume on playback is good. When I use the NR70V speaker the volume is too low.
Is there any way I can boost the volume on the orginal file before converting it with Kinoma Producer. Looked at Virtual Dub, but couldn't see any way to do it with that program.

On the NR70, T665 and SJ33 models you have the option of encoding for the stereo headphone output (Clie Audio) or the enhanced speaker output (Yamaha ADPCM).
If you encode the video to play sound out the headphones (Clie Audio), the speaker volume will be very low. If you want to play out the speaker instead, use the Yamaha sound option.
Note that Yamaha ADPCM is also compatible with the T615 and NX/NZ series. While Clie Audio is compatible with the old N710/N760 and other models using the MP3 Audio adapter.
It would be nice if you could encode both types of audio, then pick which one you want during playback, but this is not possible.
You can dynamically compress and boost the hell out of the stereo audio before encoding for more output, but this still results in pretty weak speaker output and poorer quality sound through the phones.
To boost the audio before encoding you must edit it. This can be done from within some video editing programs (Virtualdub has a gain filter), or by stripping the audio out, editing it with a sound editor, and re-muxing it with the video (virtualdub can be used for this as well).

Thanks for the info. Converted it again using Yamaha and the volume is much better through the NR70V speaker.
