mp3 audio output? #2

Closed spants closed 7 years ago

spants commented 7 years ago

Would it be possible to add support for mp3 output to buffer? This is required by a device that I would like to use.

Hi @spants, the issue during the development of this node is we find out not every browser is accepting mp3. Did you play with the ffmpeg node to get an mp3 file?

spants commented 7 years ago

Hi - I would just like to be able to do the conversion to mp3 (saved in a buffer rather than playing in a browser) from the output from the text-to-speech node in Watson.

Watson supports these Audio formats: Produces Ogg format with the opus codec (the default), Waveform Audio File Format (WAV), Free Lossless Audio Codec (FLAC), Linear 16-bit Pulse-Code Modulation (PCM), mu-law (u-law), or basic audio - and I would like to convert one of these to MP3.

If there is demand this is something that we can add. Which device is it that is requiring a mp3 output?

psyntium commented 7 years ago

i created a fork and added mp3. one of the usage is for alexa. since alexa only supports MP3 for its SSML.

@psyntium you need to accept the CLA, and default setting should remain as something that is Watson STT friendly.
