uploading mp3 files to Plum audio repository

[ambreen@ebryx.com]

Hi

When i try to upload mp3 files to plum audio repository, the files are saved as wav files. WHen I access the corresponding audio file URL, audio file format errors appear in call logs. How can I upload mp3 files to the audio repository?

Hi Ambreen,

About the IVR platform audio repository, all files that are uploaded use the following format:

http://audio.plumgroup.com/root/{8 Digit PIN}/{8 Digit PIN}_{File ID}.wav

You can read more about this here: http://www.plumvoice.com/docs/dev/plumd ... L_Examples

About the audio file format errors you are receiving, please keep in mind that these are the audio formats that we support: http://www.plumvoice.com/docs/dev/devel ... io_Formats

If your audio file is not in any of these formats, then you will encounter IVR errors.

Regards,
Plum Support

Ambreen uploaded a mp3 file with the following specs: 32kbps (32khz), mono, CBR mp3, 926 kb. When posted on the Plum hosted site, she got an error message similar to:

"Attempting to fetch http://audio.plumgroup.com/root/6795654 ... 544_31.wav
• Audio segment from the URL http://audio.plumgroup.com/root/6795654 ... 544_31.wav added to prompt queue
File: http://audio.plumgroup.com/root/6795654 ... 544_31.wav not WAV/RIFF format
• Unrecognized format in WavDecoder
Failure during pvxPromptConvertCopySource
received event: connection.disconnect.hangup: "

Note that the above error message was for a larger file, 3 mb, and we thought it might be due to size. However, even when reduced below 1mb, there were the same errors.

Ambreen adds: "I placed the smaller audio file on another URL (where I have saved our proxy etc) with its extensions as .MP3 and used its URL in the script. The file was played back fine in the call." The drawback of this is possible delays in playbacks if the Plum Server needs to look on the net for the audio files.

THUS: How can we get our mp3 files saved on Plum's storage in a file format that it can recognize?

Hi dhansen,

The IVR post earlier wasn't entirely accurate. You are not able to upload .mp3 files to the audio repository. These files would have to be converted into .wav files ( in one of the correct audio formats for .wav files shown in http://www.plumvoice.com/docs/dev/devel ... io_Formats ) before being uploaded to the IVR audio repository.

so the instructions stating that mp3 files are compatible is inaccurate? I'm referring to this: http://www.plumvoice.com/docs/dev/devel ... io_Formats, where mp3 is listed.

Our problem is the quality of the sound we get when uploaded with 8khz. What is the format that we can use with Plum that gives the BEST quality sound?

Thanks, David

Hi David,

To clarify, this IVR document ( http://www.plumvoice.com/docs/dev/devel ... io_Formats ) lists the supported audio formats when using the IVR tag, <audio>.

However, for the IVR audio repository, you would have to upload .wav files in one of the following formats:

* 8 kHz 16-bit linear PCM WAV (*.wav)
* 8 kHz 8-bit µ-law WAV (*.wav)
* 8 kHz 8-bit a-law WAV (*.wav)

As for producing audio files that have the best quality sound, we recommend that you produce audio files with a format of 8kHz 16-bit mono.

Hope this helps!

Hi dobara,

When using the audio repository, you must upload .WAV files. However, you may use .MP3 files with the <audio> tag if you upload your MP3 to your own server.
