- don't use `auto` unless needed.
- use `String` for `std::string` (this is typedef'd in ta-utils.h).
- prefer using operator for String (std::string) comparisons (a=="").
- if you have to work with C strings, only use safe C string operations:
- snprintf
- strncpy
- strncat
- any other operation which specifies a limit
some files (particularly the ones in `src/engine/platform/sound` and `extern/`) don't follow this style.

# to-do for 0.6pre1.5-0.6pre2
- rewrite the system name detection function anyway
- this involves the addition of a new "system" field in the song (which solves the problem)
- songs made in older versions will go through old system name detection for compatibility
- Game Boy envelope macro/sequence
- volume commands should work on Game Boy
- ability to customize `OFF`, `===` and `REL`
- stereo separation control for AY

In Furnace, these samples can be generated by importing a .wav (think of it as an higher quality MP3) file.
## supported systems
## supported chips
As of Furnace 0.6, the following sound chips have sample support:
- NES/Ricoh 2A03 (with DPCM support and only on channel 5)
- Sega Genesis/YM2612 (channel 6 only; but only if there exists a `1701` effect that gets played on or before a trigger for a sample, or if you are using an instrument with Sample type)
- PC Engine/TurboGrafx 16/Huc6280 (same conditions as above)
- Amiga/Paula (on all channels)
- Arcade/SEGA PCM (same as above)
- Neo Geo/Neo Geo CD (on the last 7 channels (6 if you are using Neo Geo CD) only and can be resampled the same way as above)
- Seta/Allumer X1-010 (same as YM2612)
- Atari Lynx
- MSM6258 and MSM6295
- YMU759/MA-2 (last channel only)
- QSound
- ZX Spectrum 48k
- RF5C68
- WonderSwan
- Tildearrow Sound Unit
- VERA (last channel only)
- Y8590 (last channel only)
- And a few more that I've forgotten to mention.
as of Furnace 0.6, the following sound chips have sample support:
Furnace also has a feature where you can make an Amiga formarted instrument on the YM2612 and Huc6280 to resample a sample you have in the module.
- NES/Ricoh 2A03 (with DPCM support and only on channel 5)
- Sega Genesis/YM2612 (channel 6 only)
- PC Engine/TurboGrafx-16/HuC6280

## compatible sample mode
effect `17xx` enables/disables compatible sample mode whether supported (e.g. on Sega Genesis or PC Engine).
in this mode, samples are mapped to notes in an octave from C to B, allowing you to use up to 12 samples.
if you need to use more samples, you may change the sample bank using effect `EBxx`.
use of this mode is discouraged in favor of Sample type instruments.
## notes
due to limitations in some of those sound chips, some restrictions exist:
- Amiga: sample lengths and loop will be set to an even number, and your sample can't be longer than 131070.
- 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.
- MSM6258/MSM6295: no arbitrary frequency.
- 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.
furthermore, many of these chips have a limited amount of sample memory. check memory usage in window > statistics.
# the sample editor
@ -34,11 +59,12 @@ You can actually tweak your samples in Furnace's sample editor, which can be acc
In there, you can modify certain data pertaining to your sample, such as the:
- volume of the sample in percentage, where 100% is the current level of the sample (note that you can distort it if you put it too high)
- the sample rate, from 0Hz (no sample movement) to 65535Hz (65.5kHz).
- the sample rate.
- what frequencies to filter, along with filter level/sweep and resonance options (much like the C64)
- and many more.
The changes you make will be applied as soon as you've committed them to your sample, but they can be undoed and redoed, just like text.
# tips
If you have a sample you wanna use that is about 44100 or anything over 32000Hz, downsample the sample to 32000Hz so that the pitch of the sample in Furnace stays like the original audio file. You can do this in Audacity by going to the bottom left of the screen (If you see "Project Rate (Hz)" you are there), change the project rate to 32000Hz and save the file to wav in Audacity using "File -> Export -> Export as WAV".
if you have a sample you wanna use that is about 44100 or anything over 32000Hz, downsample the sample to 32000Hz so that the pitch of the sample in Furnace stays like the original audio file,

# Namco C163
# Namco 163 (also called N163, Namco C163, Namco 106 (sic), Namco 160 or Namco 129)
This is one of Namco's NES mappers, with up to 8 wavetable channels. It has also 128 byte of internal RAM, and both channel register and wavetables are stored here. Wavetables are variable size and freely allocable anywhere in RAM, it means it can use part of or continuously pre-loaded waveform and its sequences in RAM. But waveform RAM area becomes smaller as more channels are activated; as channel registers consumes 8 bytes for each channel. You must avoid conflict with channel register area and waveform for avoid broken channel playback.

# Yamaha OPZ (YM2414)
**disclaimer: despite the name, this has nothing to do with teenage engineering's OP-Z synth!**
this is the YM2151's little-known successor, used in the Yamaha TX81Z and a few other Yamaha synthesizers. oh, and the Korg Z3 too.
it adds these features on top of the YM2151:

Wavetable playback needs to paired with envelope, similar to AY PSG, but shapes are stored in RAM and as such are user-definable.
In furnace, this chip can be configured for original arcade mono output or stereo output - it simulates early 'incorrect' emulation on some mono hardware, but it is also based on the assumption that each channel is connected to each output.

Rather than having a dedicated sound synthesizer, early ZX Spectrum models had one piezo beeper, controlled by Z80 CPU and ULA chip. It's capabilities should be on par with an IBM PC speaker... right?
Not really - very soon talented programmers found out ways to output much more than one square wave channel. A lot of ZX beeper routines do exist, as of 0.6pre1 Furnace supports only one - Follin-like engine with 6 channels of narrow pulse wave and click drums.

read sequentially.
read length, loop and then release (1 byte).
if it is a 2-byte macro, read a dummy byte.
first byte determines what to read next:
then read data.
## binary command stream
read channel, command and values.
if channel is 80 or higher, then it is a special command:
```

N: note
V: volume
I: instrument
EEE: effect count (0-7)
fb xx xx xx xx: set tick rate
fc xx xx: wait xxxx ticks
fd xx: wait xx ticks

if you read 0, end of pattern.
otherwise read in following order:

3. instrument
4. effect and effect value
then read number of rows until next value, minus 1.
