Record Audio¶
These Steps and Step Details start and stop the Audio Recorder capability. Audio recordings can then be accessed as Execution Context Objects or Call Properties.
Whenever a recording is required on a given phone, intaQt looks up the IP address of the Raspberry Pi that is connected to the phone in the AndroidDevices configuration. intaQt connects to the Audio Service on the configured URL (audioServiceURL) to start, stop and eventually retrieve the recording. The recording is provided as a single channel (mono), 8-bit unsigned *.wav file with an 8 kHz sample rate and is included as an attachment in the Reports Folder. This uncompressed, low-quality audio format is sufficient for speech channel recordings.
The recordings can be later used with:
-
Speech Channel Monitoring, which analyzes speech channel quality.
-
Audio Matching, which compares the degree of similarity between a given audio recording and the reference files.
These Steps and Step Details are members optional, which means that they can be overwritten by Custom Implementations.
Important! intaQt Audio Service only supports *.wav files with 8-bit unsigned, mono, 8kHz sample rate.

Audio Recording Step Details ¶
Audio Recording Step Details enable the recording of a voice call, or a portion of it. These Step Details must be nested within a Voice Call Compound Step.
Syntax
1 2 3 4 5 6 7 8 9 10 | // The caller records the entire call from when it starts dialing //until the call disconnects * caller records audio from dial to disconnect // The caller records the ringback tone * caller records audio from dial to connect // The caller records the call itself, but not the ringback tone * caller records audio from connect to disconnect // The callee records the incoming call * callee records audio from connect to disconnect |
