Turbine Test and Demo Application

The Turbine Test & Demo Application

The Turbine Test and Demo Application is a PC application that allows you play audio files directly from the Turbine station without connection to any server. It also allows you to do audio recordings to be used for trouble shooting if there are issues related to audio in the Turbine station.

The application has seven options:

• Test Mode View
• Demo Mode View
• Performance View
• Audio Lines
• AudioClient Instances
• Audio Streams
• AudioProcessing

Demo Mode requires that an additional audio file package (vsf-demo-media package) is uploaded to the station. Test Mode will work without this package.

Audio Recordings

On the Turbine devices it is possible for debugging purposes to record the audio, and store the audio files on the device it self.

This could be helpful when experiencing audio quality issues. The device will record what it is playing, picking up and what it is sending to the other participant of the conversation after echo- and noise cancellation have been applied.

• Start Recording: New recording starts and timer counter shows time of running recording
• Stop Recording: Stop recording and writeout wav headers to .wav files.
• Download Recordings: Click on link and all three recoding files are downloaded to PC. Check Status window for destination

Audio Recording

The recorded files:

• AecSignalMicIn.wav: Recorded signal direct from mic (HW Codec ADC). This signal is only processed by HW Codec by Gain blocks and Filter blocks.
• AecSignalOut.wav: Signal out from AEC filter and software gain blocks. This is the real signal sent to far-end station in conversation.
• AecSignalToSpeaker.wav: Signal from far-end station in conversation after decoding audio codec. Played directly to speaker and used as AEC reference signal.

Prefix: Add a filename prefix for all recordings for easy doing a series of recordings and label the files.

Demo Mode View

From the Demo Mode View tab you can play audio clips of prerecorded speech, music and alarm signals. In order to use the Demo Mode View, a Demo Media Package must be installed in the Turbine device.
