+-- This is not its final form
+--
+-- * Separate I2S->WAV and WAV->I2S into separate entities
+-- * Queues should carry integers, not bytes
+-- * Queues should allocate blocks rather than individual items (its a bit slow)
+-- * Floating point error accumulation causes MCLK drift
+-- * More sanity checks on file format (ensure sample width divisible by 8)
