First, as this is my forst posting to the list: Chris, Kevin and Hans, thank you very much for all your great work on the ivtv project!
I've been using a long string of versions from Chris, and currently 0.2.0-rc3 through Gentoo. (Linux-kernel 2.6.10) Common to all of them is an annoyingly high amount of treble, so much that I have to turn down the treble on the amplifier when viewing the recordings. Likewise, there is too little bass. To verify that the problem is in the recordings and not the replaying, I have extracted the sound-stream and played it on a different system, aswell as recording it to a CD and replaying that in a ordinary CD-player. I have also tried making a DVD from a recording, using Nero, and it sounds awfull as well. I'm using Mythtv for recording. Other than the setup by myth, I have the following in my startup-scripts: (I'm in Denmark - PAL) ivtvctl -v input=7,output=1 ivtvctl -y volume=58880 In case someone wonders what it sounds like, I have placed an 120 second example clip here in a few formats: http://www.grouleff.com/~mg/ivtv/. They were created using... ffmpeg -i 1002_20041230220500_20041230223000.nuv -f wav -acodec pcm_s16le too-much-treble.wav lame -b 320 -h too-much-treble.wav too-much-treble-320.mp3 lame -b 128 -h too-much-treble.wav too-much-treble-128.mp3 Is there some way to fix this? Is there a tool to adjust the mixing of treble and bass in the input to the mpeg-encoder? >From msp3400.c it appears as if it is almost possible already and certainly feasible to adjust the treble and bass settings. If that is the way to go, I'll be happy to implement it :) -- Morten Grouleff, [EMAIL PROTECTED] ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
