If you wish to customise the audio file heard for one of Delacon's features, such as the whisper message or IVR menu, the file needs to adhere to the following file format and specifications:
File Format: .wav (Waveform Audio)
Codec: PCM_S16LE (PCM 16)
Bitrate: 128 kbps
Frequency: 8000 Hz
If your audio file is in another format, for example .mp3, it will need to be converted prior to being uploaded. This can be done using desktop audio editing software such as Audacity or by using an online resource such as CloudConvert.
If you are having difficulty in converting the audio file correctly, please contact firstname.lastname@example.org for assistance.
