Hi XDA Community
Setup:
Native Instruments Komplete Audio 6 (connected to a USB 3.1 HUB because otherwise 48V Phantom Power does not work)
Two Condenser MICs connected to INPUT 1 and INPUT2 of the USB Sound card, powered by 48V
Samsung DEX Dock
Samsung Galaxy Note 8 (Single Sim) running Android 9 (2020 May Security Updates)
Findings:
1) Signal Messenger App
recording Voice Messages seems to use 44100 Hz recording, and the USB is most likely set to 48000 Hz. This results in crackling and digital noise in the recorded audio file
i played around with the Voice Recorder (see 2) and many other things, and Signal Messenger on DEX Screen suddenly started to record nearly correctly on 48000 Hz..
No digital noise
Records Line 1 and Line 2 onto just the left side of a stereo signal. Playback of that recording plays only on Left Speaker
After rebooting, today i cannot get this behaviour back, digital noise is there and i struggle again to find a solution how to tell Android 9 to use 48000 Hz for Signal Voice Recording or any other app with the lack of settings
i tried Voice Call with Signal Messenger on DEX Screen, but the Audio was forced to Earpiece or Speakerphone, especially the other side complained about crackling in sound quality which only disappeared, when i started Signal Messenger on the Mobile Screen on the Note 8, then it used only the internal mic and the Speakerphone, and other party said the quality is really good, but not what i want with the external mics
2a) Voice Recorder (there are several) https://play.google.com/store/apps/d....app.voicenote
can choose 44100 and 48000 Hz after my USB Soundcard is recognized and it also shows recording from External Mic Notification.
If I choose 48000 Hz the sound has no crackling or digital noise, it is crystal clear, but mono, it records both inputs on a mono track, stereo setting is greyed out
if i chose 44100 Hz i have digital noise, crackling.
uses system audio drivXDA
2b) Voice Recorder (another on) https://play.google.com/store/apps/details?id=com.splendapps.voicerec
can choose 44100 and 32000 Hz and you can even chose stereo and here it works
with 44100 Hz there is digital noise, but stereo
with 32000 Hz there is no digital noise, it is a preset called FM quality and i would like to use this for voice recording for broadcasting on FM later, we run a show on the radio
3) Audio Evolution Mobile Studio DEMO Version
comes with custom audio drivers (like DAWs on Windows also use the ASIO Drivers that are invented by Steinberg Cubase)
can use all inputs from an USB soundcard for recording in any setup with any KHz or bit in mono or stereo setup
in my case this was the only tool where i can correctly record my stereo mic setup
very nice but cannot change System Settings since comes with custom LOW LATENCY driver
maybe i will buy this Actually i use Steinberg Cubase on Windows usually
4) Zoom App
i tried a Video Meeting with Zoom App on Android 9 on this Samsung Note 8 to a Windows Laptop in different country
did not work at all on DEX, crashed on the DEX screen after joining the meeting
neither external USB Soundcard worked
if you launch on the mobile only Speakerphone, Earpiece and Internal Mic is supported
video freezes for both parties if I switch to a different app and continues if i put Zoom App in foreground
5) Google Meet
runs on Samsung DEX Screen perfectly
can present my screen from DEX
did not test with external soundcard
other paties video continues to work in background
my camera that is shared to the other partie does not record if i switch Meet App to background
better than Zoom App on Android, no wonder its Google
6) WaveEditor
best Multitrack Audio Editor that I have seen so far
Works on Samsung DEX
not really for recording but for editing/cutting/postpro
Free Version has most features, but for pro editing like compressing/parametric EQ need to buy the Pro version, I am thinking about that
really good tool, I am very happy
Conclusion:
In Signal Messenger App I have also this crackling if I record a Voice Message (and it Runs on Dex), so I suppose I need to tell Android Audio Manager to use 48000 Hz on my USB Soundcard Inputs. But how? I would like to see a Audio Manager Configuration Tool, that can change this System Wide
How do I achieve this? Any Ideas are welcome. Thanks for reading and thanks for your time posting a reply. Good day.
PS, i also opened a support Case at Samsung (in Community and Support) kee p you updated if they answer.
