Alexandre Ratchov 6c1c0d3ff6 Remove unnecessary includes. From Michael W. Bombardieri <mb at ii.net>. 2017-01-03 08:05:41 +01:00

Alexandre Ratchov 7061de0250 Set device rate to calculated rate. 2016-09-30 11:01:25 +02:00
Alexandre Ratchov 2a451f9623 Fix many typos, from Michael W. Bombardieri <mb at ii.net>, thanks 2016-09-27 14:18:43 +02:00
Alexandre Ratchov 7ddb1a5fe5 Don't rely on the resampling code to calculate the number of samples 
to process, as it may produce one extra sample (to handle accumulation
of fractional samples), which would cause access to one sample past
the end of the buffer and crash aucat. Fix this by limiting the number
of samples processed to a single block.

Found by and help from Michael W. Bombardieri <mb at ii.net>. Thanks.

Alexandre Ratchov 10f6027f0f remove unused fields of resamp structure 2016-06-09 16:43:47 +02:00
Alexandre Ratchov 00ffc8f5ab Add resamp_getcnt() routine to calculate the exact number of samples 
that would be consumed and produced by the sampler rate converter. Use
it to avoid partial samples that are not properly handled. Fixes
last samples of certain files causing aucat to abort.

intermediate conversion to 2400-th of second.

Alexandre Ratchov 0798868306 To store MMC position, use samples (at device rate) as time units 
instead of 2400-ths of second. No behaviour change.

Alexandre Ratchov e606351421 Fix file block size rounding and ensure it's large enough to store a 
full audio block.

Alexandre Ratchov 028bb6e60d When resampling, use the exact resampling factor instead of the ration 
between input and output block sizes.  This was inherited from sndion,
but is not required for files because they are continuous streams of
samples and do not need to be split in blocks of equal duration.

This change makes playback/recording rate match exactly the requested
sample rate.

Alexandre Ratchov b347c52869 Flush rec buffer if there's less than one block space left and fill 
play buffer if there's less than one block of data left. No behaviour
change, as all input/output are still block-aligned.

Alexandre Ratchov 06c8f4e89f Simplify slot_fill() and slot_flush(). No behaviour change 2016-05-27 17:46:09 +02:00
Alexandre Ratchov 4772005ac1 Give the resamp_do() the exact number input and output samples and 
provide routines to calculate them. This way we don't rely on it
anymore to calculate the bytes procuded/consumed. No behaviour change.
 2016-05-27 17:36:53 +02:00
Alexandre Ratchov a6ea35ebb3 Make format conversion routines return the number of frames 
consumed on both input and output. No behaviour change.
 2016-05-26 08:16:17 +02:00
Alexandre Ratchov d6bc5ae04f Check that byte order is native only if we're using more than one 
byte per sample, check the samples are lsb-aligned only if there's
padding.
