# samples
In the context of Furnace, a sound sample (usually just referred to as a sample) is a string of numbers that hold sampled PCM audio.
In the context of Furnace, a sound sample (usually just referred to as a sample) is a string of numbers that represent sampled PCM audio.
In Furnace, these samples can be generated by importing a .wav (think of it as an higher quality MP3) file.

- NES: if on DPCM mode, only a limited selection of frequencies is available, and loop position isn't supported (only entire sample).
- SegaPCM: your sample can't be longer than 65535, and the maximum frequency is 31.25KHz.
- QSound: your sample can't be longer than 65535, and the loop length shall not be greater than 32767.
- Neo Geo (ADPCM-A): no looping supported. your samples will play at ~18.5KHz.
- Neo Geo (ADPCM-B): no loop position supported (only entire sample), and the maximum frequency is ~55KHz.
- YM2608: the maximum frequency is ~55KHz.

- ZX Spectrum Beeper: your sample can't be longer than 2048, and it always plays at ~55KHz.
- Seta/Allumer X1-010: frequency resolution is terrible in the lower end. your sample can't be longer than 131072.
