Am working on a distant server (ubuntu) via Ssh, and i want to record using pyaudio module, i have it
already installed.
My code:
import pyaudio
import wave
CHUNK = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 2
RATE = 44100
RECORD_SECONDS = 5
WAVE_OUTPUT_FILENAME = "output.wav"
p = pyaudio.PyAudio()
stream = p.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("* done recording")
stream.stop_stream()
stream.close()
p.terminate()
wf = wave.open(WAVE_OUTPUT_FILENAME, 'wb')
wf.setnchannels(CHANNELS)
wf.setsampwidth(p.get_sample_size(FORMAT))
wf.setframerate(RATE)
wf.writeframes(b''.join(frames))
wf.close()
When i run i get the following errors:
Traceback (most recent call last):
File "record.py", line 13, in <module>
stream = p.open(format=FORMAT,
File "/usr/local/lib/python3.8/dist-packages/PyAudio-0.2.11-py3.8-linux-x86_64.egg/pyaudio.py", line 750, in open
stream = Stream(self, *args, **kwargs)
File "/usr/local/lib/python3.8/dist-packages/PyAudio-0.2.11-py3.8-linux-x86_64.egg/pyaudio.py", line 441, in __init__
self._stream = pa.open(**arguments)
OSError: [Errno -9996] Invalid input device (no default output device)
I tried to change channels number to 1 but didn't work
