File Upload

To upload an audio file, use the Upload File button, which exists on the Announcements, Files, and Variable Parts pages:

File upload for audio files is a controlled process, and several checks are made to ensure that uploaded files will be able to be played by the SRP.

The SRP backend playback algorithms require audio in raw G.711 µ-law, A-law or wideband formats.

Raw G.711 files can be generated by some audio programs, but for convenience the SRP GUI allows the upload of audio files in .wav format, and will convert these files to the necessary raw format when storing the files for playback.

When uploading a file, the user must choose the audio file, the language of the audio file content, and a name that the audio file will be referred to as within the SRP GUI. The name must consist of text with only the characters: a-z, A-Z, 0-9, underscore, period, or hyphen.

File names must be unique per language, and file names are not considered case-sensitive when being uploaded. When uploading a file, a new version of a file may be uploaded by using the same name as the existing file to be replaced. This upload request must be confirmed:

On upload, if a file does not appear to be a valid sound file and cannot be converted, the file will be rejected. All files must be able to be uploaded and converted from the uploaded format to the target format(s) configured by the system administrator.

A file may be uploaded as a valid sound file, but which still may not have the appropriate criteria for SRP playback – e.g. the audio quality may be too low. In such cases the upload will continue, however the user will be warned in such cases that the audio file quality is suspect.
