AndywinXp 8d6737e16f SCUMM: DIMUSE: Increase buffer size for low latency mode 2023-01-10 21:17:23 +01:00
AndywinXp 8d0e97af70 SCUMM: DIMUSE: Implement low latency mode 
This fixes bug #13462

AndywinXp 5b18d1aa6b SCUMM: DIMUSE: Implement support for higher internal sample rates 
This lays the ground for:
* Supporting fan dubbings and self-made high quality music replacement;
* Reintroduction of support for compressed audio.

AndywinXp a7a4d9f120 SCUMM: DiMUSE: Implement antiskip system for devices with slow load times 
This code is present in all the original interpreters using Digital iMUSE, and it was implemented
in order to allow slower CD drives to fetch new data without having music skipping during load times.
This works by basically flooding the music buffer with data whenever a big resource, a voice file, or
a SMUSH movie is loaded.
Arguably this is not needed for devices using SSD drives, but since this change had its benefits on a
quite old laptop of mine, and since the memory overhead is very minimal, I have decided to implement it.

Every functionality has been implemented (audio options, text options, saving and loading).
The only thing currently missing from the menu is the thumbnail handling.

athrxx d94618f3d5 SCUMM: (DIMUSE) - fix loading of old savegames 2022-03-28 18:29:15 +02:00
Andrea Boscarino c03787f8bb SCUMM: DiMUSE: Fix possible buffer underruns 
Big thanks to athrxx for reporting this issue; the previous calculation for obtaining an optimal number for _maxQueuedStreams did not account for the differences between the sample rate targeted by the audio backend and the one targeted by DiMUSE (which is 22050Hz). 

This new formula has been tested for optimal latency and absence of underruns for all supported games and all known combinations of sample rates and output buffer sizes:
[22050, 44100, 48000, 96000], [1024, 2048, 4096, 8192].
