Wrapper for pydub AudioSegment objects. An audiosegment.AudioSegment object wraps a pydub.AudioSegment object. Any methods or properties it has, this also has. Docs are hosted by GitHub Pages, but are currently hideous. I've got to do something about them as soon as I find some time. You can also try Read The Docs, though the docs there don't seem to be building for some reason.... also something I need to look into. Up-to-date docs are also built and pushed and are in the docs folder of this repository.

QUESTION
I'm attempting to write a python project that plays multiple parts of a song at the same time.
For background information, a song is split into "stems", and then each stem is played simultaneously to recreate the full song. What I am trying to achieve is using potentiometers to control the volume of each stem, so that the user can mix songs differently. For a product relation, the StemPlayer from Kanye West is what I am trying to achieve.
I can change the volume of the overlayed song at the end, but what I want to do is change the volume of each stem using a potentiometer while the song is playing. Is this even possible using pyDub? Below is the code I have right now.
...ANSWER
Answered 2022-Feb-22 at 13:00Solved this question, I ended up using pyaudio instead of pydub. With pyaudio, I was able to define a custom stream_callback function. Within this callback function, I multiply each stem by a modifier, then add each stem to one audio output.

While trying to use audiosegment.from_file(x.mp3) to open an mp3 file and later convert it to wave format by audio.export(x.mp3, format='wav'), I face the following Couldnt DecodeError.
What could be causing this? I am using python= 3.9, pydub=0.25.1, audiosegment=0.23.0.
Thanks in advance for the help. Below is the error shown on the console.

Answered 2022-Jan-24 at 17:46I had the same problem. I read that there is some cases where mp3 files contain AAC audio, but the container format is mpeg4.
So, the solution that worked for me is:

I have a countdown in tkinter made with a label. the function receives an amount of seconds and starts a countdown to zero. When finished, an alarm sounds.
Problem: The alarm sounds at the correct time but the countdown stays at 1 second for a few more seconds before dropping to 0. How could I correct this?
...ANSWER
Answered 2021-Nov-18 at 19:34I have finally managed to correct it adding an elif for when segundos is 0 and waiting 1 millisecond more to play the sound.
QUESTION
I am looking to combine 10 audio samples in various manners (format - wav probably, but this can be changed to any format as they will be pre-recorded).
...ANSWER
Answered 2021-Oct-20 at 11:24I believe it's slow because when you loop over x, you repeat operations (the loop over y) which could be computed before the loop over x, then assembled.
QUESTION
I'm trying to set the rms level of an AudioSegment in Pydub relative to another file, before overlaying the two. The method I'm trying to use involves setting the relative rms of the first file to be +4 dB more intense than the second- I know rms isn't modifiable, but dBFS is. I'm trying to modify it with apply_gain(), but printing the rms and the dBFS doesn't show any differences before and after calling that method.
At the moment, my code looks something like:

Answered 2021-Nov-05 at 23:42I understand that apply_gain returns a modified copy of the audio segment.
So you probably must do:
QUESTION
I have a series of wav files I would like to combine and export as a single wav using Pydub. I would like the audio from the original files to play back at different times in the exported file e.g. the audio in audio_1.wav starts at time=0 in the exported file while the audio in audio_2.wav starts at time=5 instead of both starting at time=0 as the overlay function has them. Is there any way to do this? Below is the code I currently have for importing, overlaying, and exporting the audio files.
ANSWER
Answered 2021-Nov-04 at 17:26I didn't test it but based on documentation it may need overlay(..., position=5000)
BTW:
you may also add silence at the beginning to move audio

QUESTION
Today i am working on a project about incoming phone calls being transcripted and getting saved into text files, but i am also kinda new to python and python loops. I want to loop over a SQL server column and let each row loop trough the azure Speech to text service i use (all of the phonecall OID's). I have been stuck on this problem for a couple days now so i thought i might find some help here.
...ANSWER
Answered 2021-Sep-15 at 09:21If I understand your question, you have a database with lots of phone call details. One of the field value in each row is used to create the associated mp3 file. You want to do speech to text using azure on each of the mp3 file you have in your database.
So you can do it in two ways:
- Iterate though all rows in the database and create all the associted files into a folder in the local disk with the OID as your filename.
- Then write another loop to iterate through this folder and send the files for transcription to Azure Speech to Text service.
The other technique is to do everything in a single loop like the way you have shown which will require some corrections.
Ok, so now that part is clear, we can go into the speech to text part. So azure allow you to send the compressed format for transcription, which means you actually don't need to convert it into wav file.
Please have a look at the modified code below with the changes:

Install AudioSegment
You can use AudioSegment like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
