twardoch / audiostretchy Goto Github PK

I am trying to install audiostretchy with all deps like defined in Readme, but getting error
zsh: no matches found: audiostretchy[all]...

audio_file.close() is a string object and cannot be closed. Code seem to work then line removed.

hello, i keep getting this error when using audiostretchy for a wav to wav speedup. any help would be appreciated. I am running it on windows

code:
from audiostretchy.stretch import stretch_audio
stretch_audio("input.wav", "output.wav", ratio=1.1)

I am trying to sync translated audio segments with a video using timestamps returned alongside the audio segment itself from a speech to text package. However, even with the stretch ratio calculated correctly, the duration of certain audio segments become too long, particularly because of a strange long pause at the end of the audio segment. For example in the attached zip folder there is the original audio and the stretched one. When calculating the stretch ratio based on the timestamp, the result duration should be about 5-6 seconds, a stretch ratio of around 1.1. However when inputting it into the stretch audio function, the video becomes 8 seconds instead with a 3 second pause. It will be great to know what's causing the problem and if there's something I am unaware of. The relevant code and audio files are below. Thank you!

`

def generate_segment_audio(segment, speaker_id):
    start, end, translated_text = segment  # Gets start and end timestamps from the audio segment
    segment_path = os.path.join(output_dir, f'segment_{start}_{end}.wav')
    stretched_path = os.path.join(output_dir, f'segment_{start}_{end}_stretched.wav')
    duration = end - start

    # Generate the audio file with the TTS model
    model.tts_to_file(translated_text, speaker_id, segment_path, speed=speed)

    # Adjust the audio speed to match the duration
    segment_audio = AudioSegment.from_file(segment_path)
    current_duration = len(segment_audio) / 1000  # Convert to seconds
    stretch_ratio = duration / current_duration
    print(f'{stretch_ratio} = {duration} / {current_duration}')
    stretch_audio(segment_path, stretched_path, ratio=stretch_ratio)
    return segment_path

Hello, I m getting this error when trying to run audiostretchy 1.3.1.
I tried uninstalling and reinstalling it with "pip install audiostretchy[all]" but it doesn't seem to help could you tell me how to fix this please?
I am getting this error when I run : audiostretchy m1.mp3 m12.mp3 -r1.25

Hi,
First of all, thank you so much for your work, your lib is super useful for my project with ElevenLabs.

I can't wrap my head on the gap_ratio parameters. If I understand well, it's to increase the silence length in audio, isn't it?
So if I want to slow down a speech by 30% and increase the silence length by 2 (or 100%) I would use this command:
audiostretchy tests_audio.wav test_audio-1.3.wav -r 1.3 -g 2
But it doesn't seem to increase the silence. I feel I'm missing something...
Thanks for your help!

I ran a linux docker image where I was using audiostretchy package and got this error:

How can I fix this such that it works? The audiostretchy package was working on Mac, so it must be an OS / system package issue.

Ran an ldd in the machine and got: not a dynamic executable

When I stretch an audio with a ratio different from 0.5 in the interval ]0; 1[ the audio size is indeed accelerated but the duration doesn't change. For example when do that in python:

stretch_audio("input.wav", "output.wav", ratio=0.7)

The output.wav file has the same duration as input.wav, but the beginning is correctly accelerated. There is a silence to fill it.

I plot a graph with the ratio on the x-axis (here there was a 0.1 difference between each calculation) and the time on the y-axis. You can see that there are steps and that the duration doesn't change for "special" values :

pip install audiostretchy[all]

This doesn't work and return
