[Feature]: Microphone Support Without Termux-API

[zairullahdev]

Feature description

I know this ridiculous, but it's will help to make some program (packages) record from termux

Additional information

Maybe

[yingshaoxo]

Why even after I installed termux-api by using pkg install termux-api

Then I run termux-microphone-record -l 3

It will do nothing?

It did not ask my microphone permission

I tested both android 13 and android 9, no success.

@yingshaoxo termux-api is a command line frontend which doesn't work without https://f-droid.org/packages/com.termux.api/ application.

As for the this ticket itself,

it's will help to make some program (packages) record from termux

the microphone recording is already supported by PulseAudio. Just need to grant microphone permission via Termux:API app and then load module-sles-source PulseAudio module. So basically everything that was possible to be done is done.

I'm closing this issue.

@sylirre So PulseAudio recording is already supported as long Termux:API apps and packages installed?

[sylirre]

Yes, PulseAudio supports recording, just by default it uses only module-sles-sink which does output. The module module-sles-source processes input (microphone) and it needs to be manually loaded via pactl (after granting microphone permission for api app).

Termux:API is needed only to propagate the microphone permission to Termux application.

However the everything above is applicable only to PulseAudio and pulseaudio-based programs.

ALSA was never supported and won't be as it is kernel-based audio interface, is not necessarily available on Android devices and requires root for use.

If you have problems with getting PulseAudio microphone recording to work, open issue at https://github.com/termux/termux-packages.

Here an example which shows two possible states of source module. The first command was run without microphone permission and another one after granting permission to the Termux:API.

I solved this problem by doing:

1. Install LinuxDeploy apk; Install busybox apk, install busybox payloads, reboot your phone

   • https://github.com/meefik/linuxdeploy/releases/tag/2.6.0

   • https://github.com/meefik/busybox/releases/tag/1.34.1

2. Select Ubuntu, bionic, File, image size 60GB, set username and password, enable ssh, enable vnc gui, select xfce. Hit the install button, hit the configure button, hit the start button.

3. Install "termux" apk, install "com.termux.api" apk

   • https://github.com/termux/termux-app/releases/tag/v0.118.0

   • https://github.com/termux/termux-api/releases/tag/v0.50.1

4. In termux

   
   pkg update
   
   pkg install pulseaudio
   
   pkg install termux-api
   
   
   
   termux-microphone-record -l 3
   
   
   
   pulseaudio --start --exit-idle-time=-1
   
   pacmd load-module module-native-protocol-tcp auth-ip-acl=127.0.0.1
   
   pacmd load-module module-sles-source
   
   pactl load-module module-sles-source
   
   ```
   
   

5. In LinuxDeploy system, add "export PULSE_SERVER=127.0.0.1" to the end of "/etc/profile", do a reboot

6. Use fakestandby apk to make sure the network is always on:

   • https://github.com/JonasBernard/FakeStandby/releases/tag/v1.4.0

   • When the device screen is off, it can only use LAN, ping anything else will fail meefik/linuxdeploy#1373

7. Now when you use vnc enter your linux system, you should be able to use microphone and speaker without any problems.
