3.3.3 Audio Streaming

The OA7000 firmware can be used to stream audio in the following manner:

  1. In the Func Test tab of the OA7000 GUI (Figure 3-16), click the Speaker button to select the audio file. The Wav format is supported.
  2. If the audio is playing, PLAY is displayed on the right side of volume scroll bar. When the play is over, DONE is displayed, and if reading audio file failed NO FILE is displayed.
  3. The user can change the volume via the scroll bar. (Speaker: –62 dB to approximately 4 dB)

The onboard microphone can be used with the OA7000 firmware to record and store an audio stream:

  1. In the Func Test tab of the OA7000 GUI, click the Mic button (Figure 3-17), start to record the stream.
  2. Click the Mic button again to stop recording.
  3. The recorded file will be stored in the audio_stream file at directory ..\MFT.
    Note: The format supported is PCM, the sample-rate is 16 kHz.
  4. The user can change the volume via the scroll bar. (Microphone: –17 dB to approximately 29 dB)
