FamiTracker won't load my .wav file for DPCM

I am just starting to learn about incorporating sound into my games but FamiTracker isn't working properly. I am trying to load a .wav DPCM sample but all I hear is silence. I loaded a .wav file that someone else used that worked just fine. How come some .wav files seem to load just fine while others don't?

Have you tried asking this here?

Also, might want to include what version of FamiTracker you're using and possibly even the WAV that doesn't import properly.

I'd try opening it in an audio editor, then save as a WAV. It's not uncommon for an audio file's format to not match it's extension. Without having access to the wav files, we can only guess.

I am using the latest version of FamiTracker (v0.4.3). I checked its properties and indeed it is a WAV file. As an experiment, I am attempting to load the audio file I attached here.

1. It's stereo. Try converting it to mono.
2. It's at 44100 Hz. Try sampling it down to one of the sample rates that the NES supports.
3. It's longer than 32768 samples, the limit for a sample on the NES. You might have to break it into two samples.
4. It's quiet. Try "normalizing" the file, or amplifying it such that the tallest peak is at full volume. For this wave, you'll need to amplify it by about 26 dB.

Thank you. It works now. It needed to be louder. I have to cut it into smaller pieces like you said.

tepples, the Famitracker WAV import will resample to the specified target samplerate. It is fine to use a 44.1kHz WAV as input. The only advantage to resampling ahead of time is you can choose the resampling method instead of whatever Famitracker does (if it's inadequate somehow).

That and resampling in advance makes it easier to see if the sample is too long.

Moreover, the new resampler uses a Hamming-windowed sinc kernel in a polyphase FIR filter with a reasonable kernel size, so it should be good enough—no more nearest neighbor interpolation/straight decimation.
