# ft2play 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 - This is <i>not</i> the same replayer/mixer code used in the FT2 clone - The accuracy has only been compared against a few songs - The code may not be 100% safe for use as a replayer in other projects, and as such I recommend to use this only for reference # How to test accuracy 1) Open FT2.08 or FT2.09 (use a fresh program start for every render) and load a song. Make sure "16-bit mixing", "Stereo" and "Interpolation" is enabled in the config screen. 2) Save as WAV (freq=44100Hz, amp=4) 3) Render the same song to WAV using ft2play (f.ex. "ft2play mysong.xm --render-to-wav") 4) 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. :)
