SFOS has introduced an option to record phone calls (finally! thank you Jolla!). However, no matter how I try, the resulting recordings are always silent. I tried pressing the button immediately after dialing, immediately after answering and half way through the call and the result is always the same: a recording of the correct length and with the correct tags but silent.

I went as far as inspecting the recordings in a binary editor to see if this might be just a playback issue but the files are genuinely full of just low volume noise (the values oscillate just one or two bits around zero).

I had dpurgin's Call Recorder installed before and thought, maybe there is a conflict. But uninstalling it and rebooting the phone has made no difference.

For me recordings are silent as well.

I seem dont have this problem but I prefer can save them in sdcard

@TMavica, err, how? I don't see an option to choose the target folder...

No. I mean I want this option

We lack a setting for choosing where to store captured content (photos, videos, recordings). But it is on the team backlog, hopefully soon we'll have it implemented.

Hello i give my observation here about the theme call recording. I don't if it's exactly the same issue.

i have just a remark, the sound signal of the call-recording is generally too weak. To understand the caller (means me) i should amplify the signal with 20db. And then the person who is called, is so weak that we need to amplify to more than 24db. Is it by all devices the same?

Has jolla verified it for all type of devices after programming? i don't want to criticize, but for such a weak recorded signal, i can't represent me, that is just an isolated case in all sfos ecosystem... I have a jp1 with the last sfos

I did my observation first in this thread. It may be a duplicate, if at the end the recording has no silence but a weak signal.

I let person in charge (means jolla) to set this mentioned thread in duplicate.
And please no one take initiative too shortly, until there we know that's no 2 different bugs for sure.

I have this issue too. Too low almost inausible recording levels. Is the recording done from correct stream (routed correctly) or is it what is picked up from the handset speaker and handset mic? If it is correct stream then the audiolevels need to be adjusted. Jolla 1 and Iijoki. UPDATE: I do not have headset or bluetooth headset connected nor speaker on. All of them affect audio routing and should be tested separately!

@alloj i think headset or not headset the record should be well adjusted for the weakest interface too. and especially for hearing it on a computer.
Furthermore and wonder why it is on wave format too. why not flac ogg or i don't know what else...

pichlo gravatar image is now out and the release notes say this feature is enabled in Jolla C and Aqua Fish.

No Jolla 1 then :(

Closing this question as irrelevant.

its 'tracked by jolla' and you say its irrelevant?

mettska ( 2016-07-31 23:27:13 +0300 )edit

reopened it because it's tracked by Jolla - so they may want to enable the feature for Jolla1 in the future, too.
