A UserDataAudio is a way for the user to manually supply raw audio samples.
remove_after_read means the data will be removed if read once. Else data will be stored (enable looping and seeking). Expects data as 16 bit signed (word); Example for stereo: 1.word = 1.channel,2.word = 2.channel, 3.word = 1.channel,4.word = 2.channel, etc.

void UserDataAudio::append | ( | DatagramIterator * | src, |
int | n = 0x40000000 |
||
) |
Appends audio samples to the buffer from a datagram.
This is intended to make it easy to send streaming raw audio over a network.

References append(), DatagramIterator::get_int16(), and DatagramIterator::get_remaining_size().
void UserDataAudio::append | ( | const string & | str | ) |
Appends audio samples to the buffer from a string.
The samples must be stored little-endian in the string. This is not particularly efficient, but it may be convenient to deal with samples in python.
Definition at line 130 of file userDataAudio.cxx.
References done().
void UserDataAudio::done | ( | ) |
Promises not to append any more samples, ie, this marks the end of the audio stream.
