`echos` is a bizarre effect that has never worked due to a bug
that overwrote the input samples before using them).
It's been "fixed" in sox_ng to do what it says in the manual and
comments but
1) It's odd, not a classic effect and seems more like a coding
enthusiasm than a useful effect
2) It is exactly the same as "echo" with different (and more) parameters
I'm thinking of removing it as useless and distracting baggage.
There are other reasons to start thinking of a major release 15.0.0;
nothing startling but a few non-backward-compatible changes are beckoning
like making `silence` trim from the silence point instead of 0.02
seconds after it,
not something we can put in 14.X because at least one artist has already
used this discrepancy to achieve the result they wanted.
`chorus` has also never worked and has been fixed. Twice.
See the waveform images in comment

but it is not a chorus, which is the addition of delayed and detuned
version of the same signal;
it is a simple flanger, of which we already have a much better one by
Rob Sykes,
which can probably be parameterized to do the same as `chorus`,
So, if a major release is looming, we could replace the flanging
`chorus` with a real chorus.
14.4.X and 14.5.X should probably leave them making the same horrible
noises as before
and in theory 14.6 should too. Whether making them work as described is
a bug fix or a
non-backward-compatible change is debatable. Sorry, I worry about these
things.
So my question is: despite the fact that neither `echos` nor `chorus`
has ever worked,
has anyone ever used them to advantage? i.e. Is there any reason to keep
them?
