1a4c0541d7 Change name timestamp_raw fuinction to htimestamp to follow the convention used in the rest of the library: that's the current convention (prefix the name with alsapcm_ for PCM methods). 2021-04-02 13:42:51 +02:00

8abf06bedf Prevent hang on close after capturing audio 
Currently, after recording audio using pyalsaaudio, the client is unable to close the device.

The reason is that PulseAudio client tries to drain the pipe to the PulseAudio server (presumably in order to prevent Broken Pipe error) on closing. That will never finish since new data will always arrive in the pipe.

Worse, the __del__ handler was auto-closing and thus auto-hanging.

Therefore, pause before de-allocating.

40a1219dac Support 24bit audio 
SND_PCM_FORMAT_S24_LE and similar are for 24bit ints packed in 4-bytes each.
There is a similar family of formats for 3-bytes packed data (as stored in 24bit wave files).

This commit:
 - adds S24_3LE, S24_3BE, U24_3LE, U24_3BE PCM formats to the alsaaudio.c
 - updates documentation
 - updates playwav.py to correctly play typical 24Bit PCM wave files

Closes #38

2314aaeb7e Add functions for listing cards and their names 
The cards() method does not guarantee that the index in its return
value is the same as the actual card index. Provide a way to get this
information in the form of a card_indexes() function, returning a
list of available card indexes.

Add another method, card_name(), which, given a card index, returns
the short and long names of that card.

bf24ec65ca Add a method for setting enums 
Add a method, setenum(), for setting the value of an enumerated mixer
element. The argument is an integer index into the list of possible
values returned by getenum().
