ft2play
Direct, bit-accurate C port of FT2.09's XM replayer (SB16/WAV render mode).
The project contains example code in the ft2play folder on how to interface with the API.
Notes
- To compile ft2play (the test program) on macOS/Linux, you need SDL2
- This is not the same replayer/mixer code used in the FT2 clone (the FT2 clone also uses a port, but it has some audio precision improvements)
- The accuracy has only been compared against a few songs
- The code may not be 100% safe to use as a replayer in other projects, and as such I recommend to use this only for reference
- The mixing amplification is set to 4x per default (same value as FT2), and this is a bit low. I recommend calling
setAmp(10)afterinitMusic().
How to test accuracy
- Open FT2.08 or FT2.09 (use a fresh program start for every render) and load an XM/MOD module. Make sure "16-bit mixing", "Stereo" and "Interpolation" are enabled in the config screen
- Save as WAV (Freq. = 44100, Amp. = 4)
- Render the same song to WAV using ft2play (f.ex. "ft2play mysong.xm --render-to-wav")
- Use a program capable of verifying the binary integrity between the two output files. If they differ, you found a problem and should create a new issue for this project on GitHub :)
