Dear group members,
Questions from a fresh member. I want to make a solution
that does the following on XP and Vista:
1) Appears as a sound card driver in the control panel
and in audio players.
2) Has a user interface where the user chooses the real
sound card and API to use (WDM, MME, Asio, DirectSound, Wasapi etc).
The open source library Port Audio will be used to stream
waveformatextensible audio streams - with or without the
waveformatextensible header.
3) Receives uncoded audio when selected as the driver.
4) Does some signal processing (DSP). A lot of RAM and a
lot of CPU will be used in certain cases. This is the main purpose of
the solution.
5) Has a user interface where the user can start, stop,
change the signal processing. And other things.
6) Ports the audio to real sound card drivers by using
open source library Port Audio.
7) Keeps the audio stream bit-perfect exept for the
intended DSP. System requirements should be taken care of by the
choosen sound card and audio API.
The solution doesn't have to be able to play from
multiple sources simultaneously.
Similar functionality does exist in the form of VST
plugins and DirectX plugins, but the plugin strategy has serious
limitations and problems for a lot of users.
