Need Help: Sound recording issue with pyaudio

[tathastu871]

Problem description

Created a pyaudio script t.py to record sound and export it as wav file. Problem:In termux the file shows that it started recording but strucks at it and does not stop and requires stopping script with ctrl+z while ctrl+c did not workit does not write any recording to wav. Means no recording. The script is made to record 5 seconds of audio

Script content:

import pyaudio
import wave

FORMAT = pyaudio.paInt16
CHANNELS = 2
RATE = 44100
CHUNK = 1024
RECORD_SECONDS = 5
WAVE_OUTPUT_FILENAME = "file.wav"

audio = pyaudio.PyAudio()

# start Recording
stream = audio.open(format=FORMAT, channels=CHANNELS,
                rate=RATE, input=True,
                frames_per_buffer=CHUNK)
print ("recording...")

frames = []

for i in range(0, int(RATE / CHUNK * RECORD_SECONDS)):
    data = stream.read(CHUNK)
    frames.append(data)
print ("finished recording")


# stop Recording
stream.stop_stream()
stream.close()
audio.terminate()

waveFile = wave.open(WAVE_OUTPUT_FILENAME, 'wb')
waveFile.setnchannels(CHANNELS)
waveFile.setsampwidth(audio.get_sample_size(FORMAT))
waveFile.setframerate(RATE)
waveFile.writeframes(b''.join(frames))
waveFile.close()

Steps to reproduce

Expected behavior

Recording of 5 seconds audio in wav file Additional information

Tried solution: Installed ubuntu on termux with vnc server x11 working and on it tried to run the script, and following error is obtained: Error log from ubuntu installed on termux is given below

Then tried another solution dbus-launch --exit-with-session pulseaudio --start --daemon as non root also tried dbus-launch --exit-with-session pulseaudio --start --daemon --system --disallow-exit as root user python t.py This time script ran and stopped after 5 seconds and file.wav is also created but it was mute no audio was actually recorded.

recording...
finished recording

ls results shown file.wav but it was having no sound.

However on termux script keeps working infinitely and does not stop after 5 seconds and we need to force stop it with ctrl+z, while with ubuntu on termux script rans records and stops and creates output but is muted or no actual sound recorded Termux is been provided with microphone access permission using termux-microphone-record api.

Other solutions tried: sudo jackd -d alsa to run jack server but in ended with following error:

Termux

Try to launch pulseaudio daemon manually and load module-sles-source.

pulseaudio &
pactl load-module module-sles-source

Ubuntu

No, Pulseaudio won't work here. Termux uses audio drivers compatible with Android OS, specifically ones which use OpenSLES and AAudio. Ubuntu doesn't have them. But even if has, they won't be compatible with Android's Hardware Abstraction Layer.

ALSA won't work either. Most Android devices do not have support for it on kernel level, others which have it will require root in order to access devices exposed through /dev.

Another thing i observed is that when the script is run in termux it gets into background and that may be reason it strucks at recording... and does not actually record and we need to ctrl+z or pkill to exit. But in ubuntu termux script does not show such behaviour. Please try executing script in your device and comment if it runs properly or not.

[its-pointless]

I think pyaudio can use portaudio api. I have portaudio working over pulseaudio in my apt repo.

[tathastu871]

I think pyaudio can use portaudio api. I have portaudio working over pulseaudio in my apt repo.

Script seems to be initialised without any errors and works till print ("recording...") line but after that instead of recording it gets into background and runs infinitely and not recording.

However this problem is only in termux and not in proot

[anishdevtech]

Any updates Because i too get this error https://github.com/termux/termux-packages/issues/17402#issue-1796107620

[truboxl]

I believe OpenSL ES source module for Pulseaudio is broken on modern Android and needs to be fixed or enhanced.

It is advised to use termux-microphone-record from termux-api package to record audio for the time being.

[VladKolerts]

still not working(

[anishdevtech]

I don't know termux team is busy or what but the issue is still same after 4years with no progress @termux please fix this asap

[TomJo2000]

Please don't ping the entire org for a "is it done yet" question.

[sylirre]

Instead of asking to "fix it asap", contribute.

[anishdevtech]

Hmm make sense I can try to fix

[anishdevtech]

I can assure you that openSl Es source modules work fine for PulseAudio They recorded audio and Pluse Audio play them too

The main issue is PyAudio is not recogniseing PulseAudio Stream for some reason

I think I have go through pyaudio code to figure how it works

[anishdevtech]

Looks like pyaudio uses PortAudio So let's see if PortAudio Recognise Plus Audio

[sylirre]

Our portaudio seems to disable all audio backends (neither supported by Termux):

TERMUX_PKG_DEPENDS="libc++"
TERMUX_PKG_EXTRA_CONFIGURE_ARGS="
--enable-cxx
--without-alsa
--without-jack
--without-oss
--without-asihpi
ac_cv_lib_pthread_pthread_create=yes
ac_cv_lib_rt_clock_gettime=yes
"

however its configure script suggests that Pulseaudio isn't supported anyway:

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)

  --with-jack             Enable support for JACK [autodetect]

  --with-dxdir            DirectX directory [/usr/local/dx7sdk]

                          both]

  --with-sysroot=DIR Search for dependent libraries within DIR
                        (or the compiler's sysroot if not specified).

README also doesn't mention pulse:

[sylirre]

This one may work: https://github.com/its-pointless/termux-packages/commit/70c4016230d87155591d7bb1b951959e06dd44e1

It is portaudio build recipe for old Termux community repo.

[anishdevtech]

Is it works anymore Someone told me it is not maintained anymore.

If it works then many issue such as =>

• Speech Recognition
• PyAudio
• etc And scope to new packages would be opened

[anishdevtech]

Installing its-pointless PortAudio for ARM

1. Update Termux Packages:

   pkg update
   pkg upgrade
   

2. Install wget:

   pkg install wget
   

3. Download PortAudio Package:

   wget https://its-pointless.github.io/files/24/dists/termux/extras/binary-arm/portaudio_20180920-1_arm.deb
   

4. Install the Package:

   dpkg -i portaudio_20180920-1_arm.deb
   

5. Fix Dependencies:

   apt --fix-broken install
   

6. Verify Installation:

   dpkg -l | grep portaudio
   

Troubleshooting

If you get this error:

ImportError: dlopen failed: library "libportaudio.so.2" not found: needed by /data/data/com.termux/files/usr/lib/python3.11/site-packages/pyaudio/_portaudio.cpython-311.so in namespace (default)

Follow these steps:

1. Locate libportaudio.so:

   find /data/data/com.termux/files/usr/lib -name "libportaudio.so*"
   

2. Create Symbolic Link:

   ln -s /data/data/com.termux/files/usr/lib/libportaudio.so /data/data/com.termux/files/usr/lib/libportaudio.so.2
   

For other cpu types you can follow same instructions just download the .deb file accordingly

[anishdevtech]

Ahh but now there is a new issue PortAudio is recogniseing PulseAudio Stream but not recording it.

[anishdevtech]

So here is a brief debugging report of what is working and what is not

PulseAudio ✅ OpenSL ES source module ✅ PortAudio ❌ PyAudio✅

How this works

OpenSl Module ------- PulseAudio ----- PortAudio ----- PyAudio

What to figure out ??

Why PortAudio is recogniseing PulseAudio Stream but not Recording it
