use case of audio processing and manipulation, providing set of tools for working with digital audio files. supports operations like time-domain slicing, frequency filtering, audio mixing, streaming, and effect application across various audio formats, making complex audio engineering tasks accessible through a pythonic interface.

🚀 Quick Start

Installation

install Sudio using pip:

pip install sudio==1.0.10

Basic Usage

an example to get you started with sudio:

import sudio
from sudio.process.fx import (
    PitchShifter, 
    Tempo, 
    ChannelMixer, 
    FadeEnvelope, 
    FadePreset
)
su = sudio.Master()

song = su.add('./Farhad Jahangiri - 5 Sobh (320).mp3')

cool_remix = (
    song[:40]
    .afx(
        PitchShifter, 
        semitones=-3
    ).afx(
        PitchShifter, 
        start=2,
        duration=0.8,
        envelope=[0.8, 2, 1]
    ).afx(
        PitchShifter, 
        start=10,
        duration=0.8,
        envelope=[0.65, 3, 1]
    ).afx(
        PitchShifter, 
        start=20,
        duration=0.8,
        envelope=[2, 0.7, 1]
    ).afx(
        PitchShifter, 
        start=30,
        duration=4,
        envelope=[1, 3, 1, 1]
    ).afx(
        Tempo,
        envelope=[1, 0.95, 1.2, 1]
    ).afx(
        FadeEnvelope, 
        start=0,
        stop=10,
        preset=FadePreset.SMOOTH_FADE_IN
    )
)

side_slide  = (
    song[:10].afx(
        ChannelMixer, 
        correlation=[[0.4, -0.6], [0, 1]]
    ).afx(
        FadeEnvelope, 
        preset=FadePreset.SMOOTH_FADE_OUT
    )
)

cool_remix = side_slide  + cool_remix 

# simple 4 band EQ
cool_remix = cool_remix[
        : '200': 'order=6, scale=0.7', 
        '200':'800':'scale=0.5', 
        '1000':'4000':'scale=0.4', 
        '4000'::'scale=0.6'
    ] 

su.export(
    cool_remix, 
    'remix.mp3', 
    quality=.8, 
    bitrate=256
    )

su.echo(cool_remix)

Original

Listen to the main track

it used effects like PitchShifter, which allows dynamic pitch alterations through static semitone shifts and dynamic pitch envelopes, Tempo for seamless time-stretching without pitch distortion, ChannelMixer to rebalance and spatialize audio channels, and FadeEnvelope for nuanced amplitude shaping. The remix workflow shows the library's flexibility by applying multiple pitch-shifting effects with varying start times and envelopes, dynamically adjusting tempo, adding a smooth fade-in, creating a side-slide effect through channel mixing, and scaling different remix sections. By chaining these effects together you can craft complex audio transformations, enabling audio remixing with just a few lines of code.
