I'm working on converting a .pcm file to a .wav file with GoldWave. I'm not sure if any other programs out there support headerless raw file types, but anyway I'm not able to hear a clean version of the file. I tried opening the file as raw, 16-bit sound with a 44.1 kHz sampling rate. All I hear is a high-pitched squeal, similar to the way rewinding an old video tape sounds, so I'm assuming the sampling rate is too high.

Any tips for playing PCM files?

Here's a screenshot:

Create a frequency spectrogram of your PCM files. If the max. shown frequency is e.g. 11025Hz, load your PCM file with a samplerate of 22050Hz, etc.
