Well Done...I listen to SID files every now and then...10x!

Great stuff, I have a couple of feature requests though :)

1. Is it possible to make a plugin version of this codec? My only reason for asking this is to change subsongs via a menu.
2. I've recently been playing with SIDPlayer and it enhances the sound loads with the stereo + spatial effect, any chance something similar can be added to this?

Cheers

I've edited the patch very slightly so that it applies cleanly against current CVS (21 April).

CODEC_DSP_ENABLE is no longer valid. Fixed to compile against CVS.

Subsong switching can be done by setting the song length to <num subsongs> * 1000 and then switch subsongs on seeking.
I'm currently playing around with another codec, and that's how I've solved it there. Seems to work.

This is a nice idea! Here is a patch for the subsong selection, each subsong now represents a second. As a result listened seconds are not displayed anymore - but who cares ;)

Comment by Rainer Sinsch (myth) - Thursday, 04 May 2006, 19:52 GMT
Just to make sure everyone understands:

If you wish to seek to subsong #0: Rewind to playing time: 0:00
If you wish to seek to subsong #1: Seek to playing time: 0:01
If you wish to seek to subsong #2: Seek to playing time: 0:02

and so on...

The real playing time is not counted anymore so the display directly reflects the subsong number.

Any chance of there being one patch for the SID and MOD players? I cannot patch the source for one player after the other. I did try entering the code into the appropriate source files manually but I ended up with SIDs being playable and MOD files not being recognized. Thanks.

Could this be implemented in main builds?

Great work, Rainer. Just love it. Any chance to implement a timing feature to play a SID file for a certain length and than switch to the next ... or better to use the songlenth.txt from the HVCS- http://www.hvsc.c64.org/ (High Voltag Sid Collection)? This would be great.
