e9be313c11 Fix latency compensation for audio data in portaudio backend
For drivers that correctly report latency values(ASIO) this should result a
much closer alignment of audio in a loopback test. Measurement and
adjustment may still be needed, especially for non-ASIO drivers.

Testing with the RME HDSP Multiface and Yamaha AG06 using ASIO drivers results
in maximum offset of a couple of samples.

f1b336b01e Add support for callback API to portaudio backend but keep blocking API as default
Don't use the callback API for now until further and wider testing.

aa713fcd83 Return meaningful error codes when PortaudioBackend fails to start
So they can be used to give a contextual error message in the GUI
2015-10-01 09:10:19 +10:00
f178152114 Use portaudio error codes in the PortaudioIO class.
Having error codes defined in PortaudioIO means it is not dependent on the
ErrorCodes in AudioBackend but it doesn't really make sense to have another
set, so just use the PA ones until they become insufficient.

4ffe8ffc0f Put Windows timer functions into PBD namespace in preparation for moving them to libpbd
Add functions for get/set the Multimedia timer resolution, although we are
really only interested in the minimum, this will facilitate testing

Put timer utility functions inside nested namespaces as they are platform
specific

77ce989dfa Pass input and output audio buffers into PortaudioBackend blocking process function
This makes it possible to reuse the method for callback based processing
2015-09-02 12:07:59 +10:00
23a490c906 Add two utility methods to abstract PortAudioBackend state
These may change as support for callback API is added

a65b1ddedc Add a DSPLoadCalculator class to the PortAudioBackend for DSP load calculation
The class uses the same algorithm as in the coreaudio and alsa backends and
should probably go into libardour at some point

8c2b9dac59 Rename several methods in PortAudioIO class
return ErrorCode's and handle them where necessary

cc7e97f296 Reindent and reformat switch statements in PortaudioBackend
This is more readable and consistent with the rest of the source files

71a1e9e90d Use translated error messages in PortaudioBackend when SR or i/o channel counts don't match requested
These errors are probably preventable but currently they do occur so at least
tell the user about them(and hope they check the error log window)

432e0073f6 Convert some error output to debug output in PortaudioBackend 2015-09-02 12:07:14 +10:00
9185978d2f Use translated error message in PortaudioBackend with failing to aquire RT perms 2015-09-02 12:07:14 +10:00
9d67d22e70 Use debug output rather than sending errors for developer relevant port errors
Most of these are not errors that are intended for the user, they are only
intended for developers so don't send them to PBD::error. The errors that may
be relevant to users should be handled in libardour or the GUI in response to
return values
