Topic: Over amplification of recording

We call a user who records a message. That message is then played to another user via our outbound call. Then, the recordings from both users are played to a third user from an outbound call. We are experiencing the over amplification of the recordings in the third outbound call. We have experimented with various cell and landline and voip phones. The result is consistent. Many times the message is very hard to understand. Is there an issue with the generational use of your mp3 files? This is something that is critical to our release.

Re: Over amplification of recording

Hi,

We are currently attempting to reproduce this issue that you have described with making outbound calls and playing voice recordings from previous outbound calls, but haven't experienced this issue with overamplification.

Could you provide us with more details on how you are reproducing this issue or tell us the application that is creating this issue?

Re: Over amplification of recording

More study suggests that what's actually happening is that our apps (the ones that record messages--the OB calls for script recording and the OB calls to signer) are somehow saving the message to the simpleDB with one URL and sending it to us via the SOAP/ws connection with a different URL.

Apparently QF creates a copy of the original at a different bitrate and that's where the distortion is coming in.

How can we ensure that the URL of the original recording, the one that is referenced in the simpleDB, is also the one whose URL is sent to us via SOAP?

Re: Over amplification of recording

Sometimes the MP3 doesn't copy correctly and the URL we get to our DB is to an empty value. Eg, on the last one we tried, the recordings for sayTargetName are all present in the PVP_MsgAcq table of the simpleDB (campaignNo 191141692). But the URLs downloaded to us were different and one of them referred to a blank MP3. Those URLs are uploaded in the csv for the target calls. So sayTargetName was only heard on 2 of the 3 target calls. Instead the other call heard the MP3's URL read out, alphanumeric by alphanumeric.

Re: Over amplification of recording

Hi,

Regarding the two different URLs you are seeing between the ones stored in the Simple Data Table and the ones downloaded to you, our developers have recently encountered this issue and are coming up with a solution.

We will let you know once we have found a resolution.

Re: Over amplification of recording

Hello,

As mentioned in the other thread, we've made adjustments so that different URLs do not get created for subsequent Insert, Update, and SOAP operations.  So, you should now be receiving the same URL everywhere.  Additionally, as to the over-amplification of recordings--we were adjusting the gain on phone recordings to get them up to a comfortable volume for web playback; we've tweaked this algorithm a bit so that clipping does not occur.  There will be amplification still, but it will hopefully not distort the audio.  Please let us know if there is anything further we can do to address these issues.

Thanks,
