README for speech-to-file
speech-to-file is a demo application for libmp3lame.js, based on the speech-to-server demo.
This demo records audio input from the microphone and encodes it client-based to MP3 data.
In difference to speech-to-server, this demo does not require a server for storing the encoded data, that is, the audio is not sent to a server, but instead stored locally into a blob/buffer.
When the recording is stopped, a download link for the encoded MP3 is triggered.
The idea for replacing the dependency of a server with a 'local' buffer is basically from the AudioRecorder demo (slightly modified, so that it also works in Firefox).
Tested with:
- Firefox (ver. 26)
- Chrome (ver. 31)
NOTE: Chrome needs to be allowed to load local files, e.g.
start with command line switch --allow-file-access-from-files
