Extremely helpful video ! kudos man!
Thank you, this tutorial was so helpful!
Awesome! thanks!
That’s so nice to see the audio modules together.
But, what if I want to do the recording and getting it out through some STT-TTS module at the runtime, without need of saving the file?
Noice ! Pratick
Very nice video, but could you turn off the pop ups. Some times it is hard to see what you are typing.
Thank you
Given a flute music file, how can we convert the music to notes and decompress the file back to audio blocks using literally any method( trained spectograms, any ML algorithm..)
How can the 'frames' object have bytes as its data type? It is a collection of Integers right? Shouldn't it be of type 'list'?
hi..what is the meaning y-axis in the 15:31??what is the meaning of that number?
woow wowww wwowowwww🤩😄😄
Hey, could you help me in my project? I'm trying to play audio from youtube videos. Using pytube I have the audio stream "" but I dont want to save in the computer, and then load in memory again. Do you know how to play this stream with pyaudio?
Which extension you are using to play the audio file in the vs code. comment the extension name.
It's called audio-preview
Thank you for that question
I’m kind of a noob. How is frames[0] of type int if frames is a bytes object? And why is the length still double if each element of frames is of type int?
Basically what the hell is the bytes class
I'm getting a ValueError every time I try and use this with my audio, is there any chance i could get some help? The error code says "ValueError: x and y must have same first dimension, but have shapes (22043,) and (44086,)", I know they need to be the same length but .reshape doesn't work and I have no idea what to do
Change your data type in "signal_array = np.frombuffer(signal_wave, dtype=np.int32)"
@@drueh5041 thanks I’ll try that
Hi, I get an error stating OSError: [Errno -9981] Input overflowed. OSError Traceback (most recent call last)
Cell In[23], line 16
14 while True:
15 i += 1
---> 16 data = stream.read(CHUNK)
17 rms = audioop.rms(data,2)
File ~/anaconda3/lib/python3.10/site-packages/pyaudio/__init__.py:570, in PyAudio.Stream.read(self, num_frames, exception_on_overflow)
567 if not self._is_input:
568 raise IOError("Not input stream",
569 paCanNotReadFromAnOutputOnlyStream)
--> 570 return pa.read_stream(self._stream, num_frames,
571 exception_on_overflow)
Could you share the code repo pls
Coding is so confusing and not consistent.
lol
Exactly... did not like the explanation at all
