+Subject: [PATCH] Fix audio choppiness on some systems
+
+Commit a41d46e816d2 ("Fix cancellation snappiness") made espeak unusable
+on the RaspberryPi due to extreme audio choppiness. This can sometimes
+be observed on some PC-type systems as well, albeit much less
+prominently.
+
+Relax the timing to the smallest value that makes it work again on the
+RaspberryPi.

+Subject: [PATCH] Fix latency-related buffer sizing
+
+Turns out that eSpeak-NG (the main user of this lib) enforces a minimum
+buffer size of 60ms which is also the default size. This explains why
+smaller LATENCY values were inducing choppiness in the audio on some
+systems. Adjust the comment accordingly,.
+
+Also make sure computed buffer sizes don't land in the middle of a
+sample frame. Doing (samplerate * channels * LATENCY) / 1000 is wrong.
+
+Both ALSA and PulseAudio provide nice abstractions for buffer sizing
+so let's use them directly. In the ALSA case in particular, we want the
+period to be 60ms, not the whole buffer, so to interleave speech audio
+computation and audio playback.
