I own the Eagles Hotel California on DVD-A and was able to rip to a wav file-

bitrate = 13824
samplerate = 96000
channels = 6
codec = PCM
encoding = lossless
bitspersample = 24
----------
37624160 samples @ 96000Hz
File size: 677 234 924 bytes


I can play the wavs using Foobar2000, no problem there. Other players, like WMP or EAC, forget it. I was wondering if there was a way to convert these wavs over to a more playable format and maybe reduce the file size to maybe 1/5 the size? Or, could I somehow someway make a audio DVD, not DVD-A of course? unsure.gif

If you resample to 44100, you will reduce file size by a factor of (approx) 2.34. If you convert to 16 bit, you will reduce file size by the additional factor of 1.5. It is almost certainly the case that you will hear no difference.

If you encode that result to LAME's standard VBR (V2) you will reduce file size by another factor of somewhere around 7. You will most likely still be unable to hear any difference.

Take your pick.

Take your pick. Of course you need the proper software to work with 6 channel, should you want to preserve that. I don't know if mp3 can deal with 6 channel files.

I wish it was that simple but when I convert it to a 16bit wav and, try playing it in wmp, it wouldn't work. I tried resampling but that didn't work either, could of been the program. Is there a program that you would recommend that could do it? Or, could it be done by converting it to DTS and making a DTS-CD?

Try foobar2000.

I guess you didn't read my message. I have Foobar2000 and it didn't work.

All these could cause problems for other players, especially the 6 channels - so 16 bit stereo will work on all players (I don't see how such an old track would be 6 channel).

If you plan to encode it to a lossy format avoid converting to 16 bit samples if possible.

Nope, you just didn't wrote you had converted with foobar2000.

With foobar2000 try:
- Preferences -> Tools -> Converter -> Prferred bit depth: 16
- Preferences -> Tools -> Converter -> Dither: always
- and then convert to wav file(s).

Sorry, I didn't but I did convert to 16bit before and no luck as far as increased compatibility. I tried what you suggested and no dice. Whats a good program that can take multichannel audio and convert it to stereo 44.1khz?

Sounds great if you ask me. The only thing that sucks about the DVD-A Hiigh Res 192khz stereo version is that, unless you have excellent front tower speakers with good woofers, the music is only piped in through the fronts and the sub doesn't even get signals. I have a SVS sub that rocks but it can't be used in that mode. mad.gif

I am not an audiophile but I do hear a difference between the regular stereo tracks and the multichannel. In the multichannel version, you can hear echos, little things like twanging of the strings on a guitar, cimbals being more noticable and pronounced, drums being more impactfull, and the vocals being clearer. Maybe it's my imagination but it sounds near to what I would hear in a concert hall live.

Besides reducing bit depth to 16, do the following with foobar2000:
- Select your tracks, rightclick and choose "Convert to..."
- "Converter Setup" window appears, enable "DSP Processing" and click on "..." button
- Add "Convert 5.1 to stereo"
- Add "Resampler (PPHS)", click "Configure" to set up resampler, choose 44100 or 48000 and select "Ultra mode"
- do the conversion to wav files.

Note: if you want to convert to mp3, you should disable bit depth reduction (as SebastianG mentioned).
