Together with SDL I also removed SDL_Mixer from my code. Now I have to reimplement playing music nad sfx using something else. I don’t want to use external libraries because MorphOS allows to play sound using its internal libraries. Unfortunately, I don't know anything about sound programming. Could something tell me what I should to use?

In directory Examples/Reggae of MorphOS SDK I found simple examples how to play an audio from disk or memory using Reggae. They are quite clear. However I would like to know if these methods are recommended for my requirements.

What I need:
1. Play from memory several short sounds at the same time.
2. Play music from disk (e.g. in WAVE format).
3. Play a sound with specified number of loops.
4. Play a sound from specified progress.
5. Check progress of playing music.
6. Stop specified sound.

Is Reggae good solution for games/demos or I should use e.g. AHI or OpenAL API?

Sorry for very basic question but... audio is not my favourite subject and I don't know anything about audio.

No need for Reggae: AmiArcadia can do all the things on your list and uses AHI (relevant code is in aa-sound.c), which is a more portable solution.

Reggae looks quite good. :) However I can learn AHI... Should I use high-level or low-level AHI interface?

[ Edited by MDW 18.12.2019 - 20:01 ]

The high-level interface is adequate for most needs; I'd suggest having a quick read of the AHI documentation first which discusses the pros and cons of each before starting coding.

Yes, this is very good idea. 👍 I have started reading the documentation and analysing simple examples.

I can't find whether AHI allows to play a sound with specified number of loops. Does AHI contains this feature or I should implement looping in my code?

If I decided to AHI API, I'd had to implement loading sound files (e.g. WAVE). In case of Reggae I don't have to do it.

What do you think about playing sounds using a sound DataTypes? It allows to loading, playing and it is portable between all Amiga-like systems.

For me, use reggae to load samples.

If the datatypes system has enough functionality for you then you may as well use that. Although parsing a WAV file is pretty straightforward really.

There are various AHIP_Loop#? tags that can be used to control looping in AHI.

I probably use Reggae for loading and playing sound. This is more elegant than AHI API and implement loading e.g. WAVE file. And I can play music in mpeg audio.

I have tried to play WAVE, MP3 files using standard datatypes from MorphOS. It works very good. However I can only PLAY and STOP sound(s). After PAUSE a sound, RESUME doens't resumed the sound.

I think I will back to AHI or Reggae. Currently I am not going to create versions for other Amiga-system. Only MorphOS.

Yes, there are 6 AHIP_Loop... I will check it.

Minuous, zukow:

I have one question. I load a 16-bit stereo sample using sound datatype, check type of the sample (function GetDTAttrs with tag SDTA_SampleType). Returned type is 0x00020002, so this is really stereo 16-bit:

soundclass.h
Code:

However if I play the sound using AHI with parameter:
Code:
tempo of the sound is too fast (probably 4x).
If I set parameter:
Code:
tempo of ths sound is correct.

What does it mean? Sound loaded using DataTypes always is converted to 8-bit?

If this is true, sound datatypes are absolutely useless. :) Now I understand why Reggae was created. :)

IIRC datatypes are always converted internally to an IFF representation. For sound files this would be 8SVX, even though there do exist IFF formats for storing 16-bit sound (eg. 16SV, AIFF).

Thank you for the clarification. :) So I won't use DataTypes. In case of sound this is useless on NextGen Amiga-like systems.
