e91918042a Don't let the ring buffer empty when seeking past end of track... 
... just allow a short stutter padded with silence in that case.

2806f40ab5 Don't let the RingBuffer run dry when seek-drag is very slow... 
... but not stopped.  This may even make the play head back up and re-play a
little bit.

111d2c8673 Can specify a minimum to maintain in the playback RingBuffer... 
... this may be more than the batch size used in ongoing playback.

It is expected that this larger batch size is used only once when priming
the queue before starting play.  But then FillBuffers() may attempt to
refill up to the minimum in case demand is outpacing supply.

Thus the new number defines a "yellow zone" for the queue.

Also rename another function used in producing the samples.

eeb5f1ec20 Revert "Fix the hiccup at the start of scrub or play at speed..." 
(It didn't really achieve what that commit comment said)

This reverts commit 26f72b110ceb07bc837eec5450084c6f5421ebb7.

b91300caf0 Bug 1947 - Clicky play when dynamically changing number of playing channels 
Rather than 'cut' (i.e. drop, not cut as in 'cut preview') channels immediately, we now only do so
if their last gain was already 0.0.  Instead they micro-fade out.  Later when the channels come back,
their last gain will be 0.0, so they will micro-fade in.

A comment explains that the code would be cleaner if we just computed gains, and not whether to
drop channels.

aaad7dd08d Bug 1932 - Scrubbing (and Play-at-speed) with WASAPI host (MSW only) or very short buffer preference (on Mac also) is very clicketty 2018-08-18 20:35:18 +01:00

26f72b110c Fix the hiccup at the start of scrub or play at speed... 
... We need to start the polling of mouse state before starting the audio
stream, and not "nudge" AudioThread, so that AudioThread primes the ring
buffer correctly, not inserting some silence.

This requires yields to timer events in AudioIO::StartStream.

11da92d668 Allow capture retries if time since Rescan() < 10s 
The time since Rescan() of recording device is the important factor,
not the "newness" of the project.

835abd9be3 bug 1885 Linux: Allow retries when opening capture 
On launch, Audacity scanning the sound system causes Pulse to grab
exclusive control of the audio device, causing the device to be
unavailable until Pulse times out and releases it.

If an attempt is made to start recording from the hardware device (hw:)
immediately after launch, PortAudio will time out before the device is
released. In this case we need to retry opening the capture stream.

(This also applies to monitoring).

1d22ca5789 Improve error message when capture stream fails 
Rather than just guessing at the cause of the error, include the actual
error string from PortAudio.

3886113b91 More efficiency in TrackTimeUpdate 2018-08-11 20:37:23 -04:00
Paul Licameli
ce1ce688ff Try to clarify real time / track time distinction in comments... 
... Rather than the confusing old terminology of "warped" time, meaning the
real time after accounting for time track, though that persists mostly in the
names of variables now mostly used only within PlaybackSchedule.

"Track" time refers to a position in a wave track, as indexed by the time
ruler.

"Real" time is indexed by the other scale of numbers drawn in the time track,
which is drawn on the screen with nonuniform spacing (so "warped" in that
sense), but it corresponds to uniform actual time.

Use local variables to avoid repeated reads of the atomic.
