- Subject: A basic, beginner's question
-
- In all the GUS SDK documentation I see a more-than-adaquate treatment of
- sound playback, but the documentation on sound recording is a bit lacking. I
- can understand the mechanics of continous digital sound playback (looping,
- rollover, etc), but I don't understand the methods to use to implement
- continous recording.
-
- I see that the actual recording is taking place via DMA directly into the
- PC's memory (rather than the GUS RAM). Is it possible to set the recording
- to loop inside of a (for example) 20K block, sending an IRQ when a rollover
- point (10K, say) is reached? It makes sense that this would be possible, but
- I don't see from the SDK docs how to set it up.
-
- Also, what is the lowest sampling rate that would allow distinguishable
- speech to be recorded? I'm looking at an application that needs to be able
- to transfer sampled speech through a _s_l_o_w_ communications connection, and
- even with ADPCM encoding I'll still need to minimize the samples...
-
- Thanks for the help, and I apologize for the beginner's questions. ;-)

-
- Hi GUS proggers.
-
- I am attempting to write some MIDI software (player, sequencer type stuff), and
- I have all the info I need on the MIDI format, and the .PAT file format.
-
- What I have not yet come across is any source code which handles the playing of
- patches (including all that enveloping and vibrato stuff).
-
- There's plenty of source for playing MODs, but does anybody out there have or
- knows of any freely available source to do such a thing?
-
- I'd luv to hear from ya...
