Upload audio files to BrowserStack real Android devices

Websites that use Web Real-Time Communication (WebRTC) technology, websites/webapps that record and process audios for speech and voice recognition, etc. use the system microphone for audio inputs.

Live enables you to test websites/webapps that require specific audio inputs, on select BrowserStack real Android devices. You can upload audio files from your system to a supported BrowserStack Android device. The uploaded audio files are used as inputs to the device microphone, to simulate the action of recording an audio. Your website under test uses the uploaded audio file as input when capturing audio using the getUserMedia API, as defined in Mozilla documentation.

• Supported devices and files
• Uploading your audio and testing your website with audio

2. On the Live toolbar, click Files & Media > Audio injection.
3. Click the play icon near the audio file name.
   When the audio file is playing, you do not hear the audio. However, your website receives the audio input from the audio file.

Additional information

• If you upload a new audio file, the new file replaces the old audio file.
• If you do not upload any new audio file for 30 days, your last uploaded file is removed and replaced with the sample audio file.
• You can switch devices during your test session on supported audio upload enabled devices. The Files & Media > Audio injection tab in the new device displays the audio file that you uploaded. You can test with the same audio file on the new device.
