HELP!! Why does Winon 3.7 Power edition, Menu audio play distorted????

greenspun.com : LUSENET : Video CD : One Thread

Whats up? Im using the winon 3.7 power edition (with the service pack upgrade)and i have sucessfully made a vcd with options and menus(wooohooo!!!). HOWEVER can someone tell me why my menu audio plays distorted( i made my main menu screen with audio, it converted a wave file to mpeg (i dont think though it made it mp3??). the stats for the audio were normal for audio on an mpeg. if anyone can help?? thanks again. Oh for the record im playing it in the pioneer 525. thanks

Did you listen to the original *.wav file? Was it clean and undistorted to begin with? Was it originally 44K/16b/stereo? If it was not, in some processes that convert to the required *.mp3, having to resample may introduce distortion most especially if the source *.wav sampling rate is not a multiple of 44.1KHz. For example an original file sampled at 10KHz may produce distortion in the final *.mp3 file that may not be present compared with another file originally sampled at 11.025KHz. There is also a setting with permissible audio formats of VCD called "joint stereo", which, if chosen, can produce some weird effects in the final .mp3 from some sources that are, say completely out-of-phase, channel-wise.

thanks for the reply. Yup it was a wave with the 44/16b/stereo. If indeed it did make it some kind of mp3 then that would explain why the pioneer did not read it. However i demuxed the still image i had with it and it had it as a simple mpa. So i still have absolutely no idea why its distorted. i do recall (trying to find the post) someone else on here had the same problem before, but i do not think they ever got a reply.

That's me. And it's true.

No one helped me! :)

Unfortunately I haven't come to any solution either. I did found a way to make the sound at least as good as one *.mpa file I found on the Internet. I used Xing Encoder and created a new stream profile under File/Stream Profile. I used the same settings as the previous file and applied it on my file.

The settings I got and used was MPEG 1 (L2), 44100Hz, Mono, 64kbits/sec

Strangely this settings is quite different from Video CDs audio settings but sound a little better than when VideoPack tries to convert a clean *.wav file.

I have tried to change the bitrate to get the perfect sound but with no luck.

At the moment I'm waiting for CDMotion for Video CD which I hope will correct this problem. VideoPack is kind of a old program and perhaps that's the reason why it don't work.
