I use a Windows 7. Before I go any deeper i am very new to audio editing. I am trying to export a song into a .wav format using the following settings, Frame Rate: 11025Hz, Mono, 16-bit PMC. The file was at first Frame Rate: 44100Hz, Stereo, 32-bit float. When I finished the editing, when I exported it to a .wav file it stayed at 32-bit float and not staying at 16-bit PMC like I edited to do so. This is really distorting the song in the game “Team Fortress 2” in which I am trying to implement into using HLDJ (Half-Life DJ). Please help and thanks for reading this.
I have no idea what “16-bit PMC” is. Assuming you mean PCM, make sure you have a mono track in Audacity. If the song is stereo, use Tracks > Stereo Track to Mono.
Then change the project rate bottom left of Audacity to 11025 Hz. This sets the sample rate (not the “frame rate”) for the exported file.
Then export using the “WAV (Microsoft) signed 16-bit PCM” choice. Please see here for how to use the File Export dialogue: http://manual.audacityteam.org/o/man/file_export_dialog.html .
Still didnt work.
If you have imported the WAV you exported back into Audacity, it will say “32-bit float” above the Mute / Solo buttons because by default Audacity expands all imported audio to 32-bit float PCM.
If you followed the instructions you were given, the file you exported will nonetheless be 16-bit PCM. You can check that by downloading a program called “MediaInfo” from http://mediainfo.sourceforge.net/en/Download/Windows . Get the version without installer, because the installer may have malware.
If that doesn’t help, make sure you have Audacity 2.0.5 from here http://audacityteam.org/download/windows then follow the instructions to the letter. If there is a problem, please say exactly what goes wrong. If there is an error message, tell us exactly what it says. “Didn’t work” tells us nothing.
This is really distorting the song.
When you reduce your sample rate to 11,025Hz, your audio is limited to half that (5512.5Hz). You’ll loose the highest audio frequencies, you’ll no longer have “high fidelity”, and music will tend to sound “dull”. (That’s a loss of frequency range, not actually distortion.) Human hearing “traditionally” goes from 20Hz to 20,000Hz for a young person with normal hearing.
You can get clipping (distortion) if the 32-bit floating-point waveform goes over 0 dB, and then you save it as a regular 16-bit WAV/PCM file. (By default, you should see a red waveform where there is potential clipping.)
I guess also that if HoffmannA really did export 32-bit float WAV then the game may not be able to cope with that, which could explain the distortion.
If you had to make the stereo track mono, make sure you do it with Tracks > Stereo Track to Mono. Don’t use the Track Drop-Down Menu to Split Stereo to Mono and export that, because that will combine the amplitude of the two tracks to make the mono file, making it too loud and probably causing clipping.
