What file formats are supported by Watson Speech to Text in Bluemix

In the Watson SpeechToText in Bluemix the sample audio files are wav. Are there other file formats that are also supported? MP3 for example

Best Regards

Both audio/flac and audio/l16 MIME types are supported. If you use the audio/l16 MIME type, specify the rate and channels. For example, "audio/l16; rate=48000; channels=2". Ensure that the rate matches the rate at which the audio is captured.

Streaming is required for audio longer than 4MB. Streaming limit is 1 GB.

See the API reference and Getting Started for more detail :)
