/**
|
|
An AudioFormat class which can use an installed version of the LAME mp3
|
|
encoder to encode a file.
|
|
|
|
This format can't read MP3s, it just writes them. Internally, the
|
|
AudioFormatWriter object that is returned writes the incoming audio data
|
|
to a temporary WAV file, and then when the writer is deleted, it invokes
|
|
the LAME executable to convert the data to an MP3, whose data is then
|
|
piped into the original OutputStream that was used when first creating
|
|
the writer.
