Encoding your audio stream

All audio streams provided should be encoded as PCM WAVE, 16khz mono. The following ffmpeg command can be used to convert your input before sending it to our API:

ffmpeg -y -i "${input_file}" \
    -ac 1 -acodec pcm_s16le -ar 16000 \
    -f wav "${output_file}"

This command can also be used in a pipe in which ${input_file} and ${output_file} can be set to “-“ for respectively stdin and stdout.
