/*
- We have two cases to consider:
-
- 1. The region has not been stretched before.
-
- In this case, we just want to read region->length() samples
- from region->start().
-
- We will create a new region of region->length() *
- tsr.time_fraction samples. The new region will have its
- start set to 0 (because it has a new audio file that begins
- at the start of the stretched area) and its ancestral_start
- set to region->start() (so that we know where to begin
- reading if we want to stretch it again).
-
- 2. The region has been stretched before.
-
- The region starts at region->start() samples into its
- (possibly previously stretched) source file. But we don't
- want to read from its source file; we want to read from the
- file it was originally stretched from.
-
- The region's source begins at region->ancestral_start()
- samples into its master source file. Thus, we need to start
- reading at region->ancestral_start() + (region->start() /
- region->stretch()) samples into the master source. This
- value will also become the ancestral_start for the new
- region.
-
- We cannot use region->ancestral_length() to establish how
- many samples to read, because it won't be up to date if the
- region has been trimmed since it was last stretched. We
- must read region->length() / region->stretch() samples and
- stretch them by tsr.time_fraction * region->stretch(), for
- a new region of region->length() * tsr.time_fraction
- samples.
-
- Case 1 is of course a special case of 2, where
- region->ancestral_start() == 0 and region->stretch() == 1.
-
- When we ask to read from a region, we supply a position on
- the global timeline. The read function calculates the
- offset into the source as (position - region->position()) +
- region->start(). This calculation is used regardless of
- whether we are reading from a master or
- previously-stretched region. In order to read from a point
- n samples into the master source, we need to provide n -
- region->start() + region->position() as our position
- argument to master_read_at().
-
- Note that region->ancestral_length() is not used.
-
- I hope this is clear.
