Here are some options I found for low-level stuff:
- I started a BAMS library (Basic Audio Mixing
Subroutines) on my hard drive. It's patterned
after Ardour's internal mixing subroutines.
- There's liboil and it's successor ORC. Before
using liboil, you should check out the rationale
for why it's now being done with ORC.
- I saw another SIMD audio processing library
recently. Looked a lot like liboil.
For a higher-level mixing library... the more I thought
about it the more I was convinced that writing a general-
purpose "mixer" library is more-or-less trying to re-write
JACK in my application space. The options I found for this
- Ingen is designed to be an audio engine, handling
all your plugins and connections and misc. DSP
- I started a Mixer class for libTritum (part of
Composite). libTritium is intended ot be a public
API... but it's not there, yet. However, this class
is pretty efficient and pretty general purpose.
Also, it's worth mentioning that many of the LAD's I talk to
think that mixing is low-level enough that such mixing
libraries are not a good idea. That judicious ad-hoc mixing
here and there is the whole art of efficient DSP.
