I have never read or played sound files with Racket, except via system calls.
Some Racketeers have implemented PortAudio. You can check the PLaneT server for
that. Precise synchronization of I/O and sound is tricky. With what kind of
programming are you familiar?

Use `racket/base' for any library that you intend to give to others.
Otherwise, use `racket' if you find it more conv
Hi everyone,
I'm a beginner in Racket and I plan to make a rhythm game.
Do you think it is possible? Would it be easy?
I don't know where to start from.
The program has to analyze sounds, and that's the hard part...
Thanks in advance.

I actually noticed a bug in the code of a large system a couple days
ago, thanks to "require"s of non-base Racket modules.
Finding the bug was prompted by a "Why does this module require *that*
module?" reaction when I was cleaning up "require"s. (Turns out someone
had mistakenly conflated tw
My experience has been the only time I benefit from #lang racket/base
over #lang racket in terms of a noticeable runtime cost is when I'm
writing little scripts and running them via "racket" on the
commandline. FWIW.

I, for one, always use "racket/base".

For student languages it might be better to use `make-evaluator'.

I don't think it should be that difficult once you get an evaluator
set up. I've done something like what you want, taking some ideas from
the handin server code. What I came up with (no fancy macros) is you
define a test specification for an assignment like this (in a #lang

Any thoughts on how, by default, timing of garbage collection cycles is
affected by whether the process is "idle".
For example, if non-GC threads are all waiting on events, might the
thread with GC be more likely to trigger a GC at that idle time, rather
than when some threads are working?
