HydrogenAudio

I downloaded some files from a website: Revelation (http://www.youtube.com/watch?v=xsNeXeTF6NM&list=PLB5B39F97B2265020&index=5//) (select pop up and right click to download). It is a wmv file. I extracted the audio into Ogg Vorbis with ffmpeg. The problem is the audio is a little low. Is there a way I can raise the audio level on the Ogg file?

Also is there a way to check what bitrate the audio is on the file from the website, so I know how high to set it when I convert it to Ogg (don't want to set it too high of bitrate on Ogg if it isn't going to help the sound).

Thanks

If you don't already have an audio editor, Audacity (http://audacity.sourceforge.net/?lang=en) is FREE!  In Audacity, you can use the Amplify or Normalize effect and adjust the volume for 0dB peaks.  That's as loud as you can go linearly (without dynamic compression, limiting or distortion/clipping). 

Note that the peak level doesn't correlate very well with perceived loudness, and many digital files are already normalized, so it might not make any difference.

I don't know...  If you are directly downloading the original WMA, you can convert bytes to bits estimate the average bitrate with the following:

Bitrate in kbps = (File Size in MBx140) /Playing Time in minutes

But, I'm not sure that will help when converting from WMA to OGG.  You'll probably have to experiment to determine how low you can go without audibly degrading the sound.
