Nodes
| sound_c | |
| content | sound.c: sound engine |
| children | static_asserts, notefreqs, sound_public_funcs |
| file reference | codestudy/tic80/sound.c:0 |
| notefreqs | |
| content | NoteFreqs: a giant array of ints, presumably some kind of conversion table. Probably generated, as it's all on one line. |
| parents | sound_c |
| file reference | codestudy/tic80/sound.c:38 |
| static_asserts | |
| content | static asserts? I've never seen these before. I'm assuming they are compile-time checks. |
| parents | sound_c |
| file reference | codestudy/tic80/sound.c:39-45 |
| sound_public_funcs | |
| content | Public functions in sound.c |
| children | tic_core_sound_tick_start, tic_api_music, tic_api_sfx, tic_core_synth_sound, tic_core_sound_tick_end |
| parents | sound_c |
| tic_api_music | |
| content | tic_api_music() |
| parents | sound_public_funcs |
| file reference | codestudy/tic80/sound.c:498-506 |
| tic_api_sfx | |
| content | tic_api_sfx |
| parents | sound_public_funcs |
| file reference | codestudy/tic80/sound.c:508-512 |
| tic_core_synth_sound | |
| content | tic_core_synth_sound() |
| children | blip_read_samples |
| parents | sound_public_funcs, tic80_sound |
| file reference | codestudy/tic80/sound.c:542-561 |
| tic_core_sound_tick_start | |
| content | tic_core_sound_tick_start() |
| parents | tick_funcs, sound_public_funcs |
| file reference | codestudy/tic80/sound.c:563-581 |
| tic_core_sound_tick_end | |
| content | tic_core_sound_tick_end() |
| parents | tick_funcs, sound_public_funcs |
| file reference | codestudy/tic80/sound.c:583-598 |
| blip_read_samples | |
| content | calls to blip_read_samples() |
| children | blip_set_rates (I believe this is how the rates are being set) |
| parents | tic_core_synth_sound |
| remarks | These are calls from a third-party library called blip-buf Looking at the README for it, this seems to handle audio re-sampling. |
| file reference | codestudy/tic80/sound.c:551-552 |
| blip_set_rates | |
| content | blip_set_rates: used to set "clock" and regular samplerates |
| parents | blip_read_samples |
| remarks | it's set somewhere outside of this file |
| tick_funcs | |
| content | A tick is a unit of time where things happen. It includes sound events and input events, among other things. |
| children | tic_core_sound_tick_start, tic_core_sound_tick_end |
| tic_c | |
| content | tic.c |
| children | tic80_sound |
| file reference | codestudy/tic80/tic.c:0 |
| tic80_sound | |
| content | tic80_sound() |
| children | studio_sound (tic80_sound is also used in sokol API calls.), tic_core_synth_sound |
| parents | tic_c |
| remarks | this seems to be a top-level sound function. |
| file reference | codestudy/tic80/tic.c:127-131 |
| studio_c | |
| content | studio.c |
| children | studio_sound |
| file reference | codestudy/tic80/studio.c:0 |
| studio_sound | |
| content | studio_sound() |
| parents | studio_c, tic80_sound |
| remarks | This seems to be called by sokol, so this might be the way sound is rendered in TIC80? |
