Audio recording quality goes bad after 1 minute, using different apps

2019-07-05, 1:18 AM

Hi all,

I have a moto Z3, no mods, last system update was 6/1/19 it says.  

 

I have an audio quality problem and it happens on more than one audio recording app, so I wonder if there is something that might have gone weird about the phone recently that could affect audio behavior.  

 

Problem is I record and the first ~1 minute sounds good and then quality gradually turns bad until its sounding like a totally compressed to death mp3 or worse. 

 

I tried all the different formats and updated/uninstalled/reinstalled the app.  

Up to here I blamed the app.

 

But then, I installed a different voice recording app, and it does the same thing.  

 

So i am now surprised and sad I dont know if i can record good audio anymore.

Has anybody heard of this?  

 

thanks so much for any help,

J

I am using the built in microphone.

Android 9

System updated to PDXS29.84-30-3, on May24

Apps used were:
1) Voice Recorder by Splend Apps, *worked great long time* until this problem started a week ago.
2) Voice Recorder by Raytechnoto Labs, does the same problem.

Both apps have the same problem, is it my phone?

I would make sure you have backed up all the Stuff on the phone to the Cloud and or a PC/Laptop and then do a ,"Factory Restore" but when it reboots do NOT let the fresh install auto-update/install your apps.Set the phone up manually.

 

I've been using Android a lot of years and after a major system update I've found if I do this the new operating system works without problems.What can happen is that old data on the phone doesn't get properly cleaned out by the update/Patched operating system.

 

Also as a new O/S gets installed some 3rd party apps may not work correctly as the apps themselves have not been updated or written for the new O/S.If one or more of your Fave apps gives problems you may have to find alternatives :/

 

 

Doing a fresh install cleans all the accumulated junk out.

 

 

HTH :)

Hi Moto408,

 

Thanks for posting. How does the sound when recording a video using the Moto Camera app? Try testing the microphone in the Moto Help app > Diagnosis > Hardware Test > Microphone. Let me know. 

 

Best regards,
Rich

Hi Rich thanks for the reply,

I found the Help app and it did the quiet volume test. Seemed ok.

I tried recording nylon string acoustic guitar and it played back normal the whole 2 minute chunk, no problem somehow.

I then recorded a sine wave from my test equipment, in case somehow this is related to the crunchy high end of electric guitar sound(?) (thats what i usually record). No problem for sine wave. Maybe its fixed?

Then i tried electric guitar and it was intermittently happening.
Sometimes it would do it, other times, to my surprise, it played back fine.

So i wondered if it was volume related, i tried at different distances from the speaker. Mostly ok occasionally bad.

I dont know if it doesnt like my riffs maybe haha

I know this is inconclusive.
Ill keep trying different things and see if there is a pattern to it.

It's some kind of ,"Phasing".Very strange.I would still do a Factory Reset just to discount any OS update funkiness.

It is a royal pain to do a factory reset. I will have to do 25 password recoveries, have to go through hell of figure out if my pics and music and recording messages are backed up, resync my games and redownload all my apps.  Id rather have my teeth drilled at the dentist than go through that and find it didnt help.  

 

Can anybody think of a way to see if anybody else has this problem? 

 

Every time I google -android 9 recording quality- it gives me 10,000 results about CALL recording feature stuff.  

 

Thanks, still bummed my phone cant record without wavy swishy deterioration.

 

Thanks for reading!

J

I got my phone hardware replaced with insurance due to a camera picture problem.  

 

The audio still sounds like the same phasered crap.  So that rules out factory reset. 

 

I went to a show and wasted my time trying to capture some of it for a friend who couldnt be there.  I forgot the video did worthless audio too.  What a waste. 

 

So..

new hardware same problem

every audio app i tried and video, built-in and third party

factory reset no help

 

Im blaming motorola and super pi$$ed. 

 

I have a motorola phone with gimped audio until my contract ends.  In a year.  

 

Thanks for listening to me :(
