Repl.it audio bindings bundle.

This package includes the go bindings and static library files needed for audio at repl.it.

Credits go to:

• libsamplerate for the C library.
• opus for opus support
• opusfile For opus file decoding
• libogg Required to build opus and used in the go bindings.
• OpenSSL Not included but is used to build opus.
• gosamplerate go bindings for libsamplerate. (modified to use CFLAGS and LDFLAGS instead of pkg-config, and to take the output buffer size as an argument to NewSource rather than setting it to the input buffer size)
• opus (the go bindings, not opus itself): Bindings for libopus. (modified to use CFLAGS and LDFLAGS in place of pkg-config)
• this stackoverflow answer which includes a short c script used to static link libm.a without libc. They borrowed it from here

Contributing

For new file support, we need the following:

• Abillity to find file/decoder samplerate (or a static samplerate).
• Abillity to get channel count of the decoder (or a static channel count).
• Abillity to read into a pcm buffer (Format can be whatever, we just need to know what the format is).
• Go bindings for the library.
• Static .a library, not .so files.
• Sources must be cited.
• If there is a pure-go version of the library just send a request for that file format over at https://repl.it/feedback, this is just for bundling c libraries with go bindings.

Note that this is not where you should report issues for audio at repl.it, instead report at https://repl.it/bugs/
