TTS sample rate

Open hipitihop opened this issue 5 years ago • 2 comments

The node UI parameters allows format selection but not sample rate. Is it possible to provide the sample rate via the incoming msg e.g.

msg.payload = "Hello world from Watson";
msg.sampleRate = 16000;
return msg;

Looks like whether you can or must supply sample rate is dependent on the selected format.

I have added this requirement to the backlog.

@chughts Thanks. Indeed some formats must specify whereas others are optional and have defaults. I'm particularly interested in WAV because I need 16000 and the default is 22050
