pedalboard is a Python library for adding effects to audio. It supports a number of common audio effects out of the box, and also allows the use of VST3® and Audio Unit plugin formats for third-party effects. It was built by Spotify's Audio Intelligence Lab to enable using studio-quality audio effects from within Python and TensorFlow.

Internally at Spotify, pedalboard is used for data augmentation to improve machine learning models. pedalboard also helps in the process of content creation, making it possible to add effects to audio without using a Digital Audio Workstation.


  • Built-in support for a number of basic audio transformations:
    • Convolution
    • Compressor
    • Chorus
    • Distortion
    • Gain
    • HighpassFilter
    • LadderFilter
    • Limiter
    • LowpassFilter
    • Phaser
    • Reverb
  • Supports VST3® plugins on macOS, Windows, and Linux (pedalboard.load_plugin)
  • Supports Audio Units on macOS
  • Strong thread-safety, memory usage, and speed guarantees
    • Releases Python's Global Interpreter Lock (GIL) to allow use of multiple CPU cores
      • No need to use multiprocessing!
    • Even when only using one thread:
      • Processes audio up to 300x faster than pySoX for single transforms, and 2-5x faster1 than SoxBindings
  • Tested compatibility with TensorFlow - can be used in tf.data pipelines!


pedalboard is available via PyPI (via Platform Wheels):

pip install pedalboard

If you are new to Python, follow INSTALLATION.md for a robust guide.


pedalboard is thoroughly tested with Python 3.6, 3.7, 3.8, 3.9, and 3.10 as well as experimental support for PyPy 7.3.

  • Linux
    • Tested heavily in production use cases at Spotify
    • Tested automatically on GitHub with VSTs
    • Platform manylinux wheels built for x86_64
    • Most Linux VSTs require a relatively modern Linux installation (with glibc > 2.27)
  • macOS
    • Tested manually with VSTs and Audio Units
    • Tested automatically on GitHub with VSTs
    • Platform wheels available for both Intel and Apple Silicon
    • Compatible with a wide range of VSTs and Audio Units
  • Windows
    • Tested automatically on GitHub with VSTs
    • Platform wheels available for amd64 (x86-84, Intel/AMD)

Plugin Compatibility

pedalboard allows loading VST3® and Audio Unit plugins, which could contain any code. Most plugins that have been tested work just fine with pedalboard, but some plugins may not work with pedalboard; at worst, some may even crash the Python interpreter without warning and with no ability to catch the error. For an ever-growing compatibility list, see COMPATIBILITY.md.

Most audio plugins are "well-behaved" and conform to a set of conventions for how audio plugins are supposed to work, but many do not conform to the VST3® or Audio Unit specifications. pedalboard attempts to detect some common programming errors in plugins and can work around many issues, including automatically detecting plugins that don't clear their internal state when asked. Even so, plugins can misbehave without pedalboard noticing.

If audio is being rendered incorrectly or if audio is "leaking" from one process() call to the next in an undesired fashion, try:

  1. Passing silence to the plugin in between calls to process(), to ensure that any reverb tails or other internal state has time to fade to silence
  2. Reloading the plugin every time audio is processed (with pedalboard.load_plugin)


A very basic example of how to use pedalboard's built-in plugins:

import soundfile as sf
from pedalboard import (

audio, sample_rate = sf.read('some-file.wav')

# Make a Pedalboard object, containing multiple plugins:
board = Pedalboard([
    Compressor(threshold_db=-50, ratio=25),
    LadderFilter(mode=LadderFilter.Mode.HPF12, cutoff_hz=900),
    Convolution("./guitar_amp.wav", 1.0),
], sample_rate=sample_rate)

# Pedalboard objects behave like lists, so you can add plugins:
board.append(Compressor(threshold_db=-25, ratio=10))

# Run the audio through this pedalboard!
effected = board(audio)

# Write the audio back as a wav file:
with sf.SoundFile('./processed-output-stereo.wav', 'w', samplerate=sample_rate, channels=len(effected.shape)) as f:

Loading a VST3® plugin and manipulating its parameters

import soundfile as sf
from pedalboard import Pedalboard, Reverb, load_plugin

# Load a VST3 package from a known path on disk:
vst = load_plugin("./VSTs/RoughRider3.vst3")

# dict_keys([
#   'sc_hpf_hz',
#   'input_lvl_db',
#   'sensitivity_db',
#   'ratio',
#   'attack_ms',
#   'release_ms',
#   'makeup_db',
#   'mix',
#   'output_lvl_db',
#   'sc_active',
#   'full_bandwidth',
#   'bypass',
#   'program',
# ])

# Set the "ratio" parameter to 15
vst.ratio = 15

# Use this VST to process some audio:
audio, sample_rate = sf.read('some-file.wav')
effected = vst(audio, sample_rate=sample_rate)

# ...or put this VST into a chain with other plugins:
board = Pedalboard([vst, Reverb()], sample_rate=sample_rate)
# ...and run that pedalboard with the same VST instance!
effected = board(audio)

  • Updated JUCE to version 6.1.4

    Updated JUCE to version 6.1.4

    update-juce: Checked out the latest version of JUCE

    Problem In order to work on this issue, an update of JUCE is first needed. The discussion there outlines why.

    Solution I simply updated the JUCE submodule to the latest stable master commit (their commit message is aptly "JUCE version 6.1.4"). I made sure to detach the HEAD in order to prevent automatically updating in the future.

    Comments Running tox, the tests on my end seem to be all good. I was unable to run lint tests but this isn't a concern for this specific PR. Lint seems to be concerned with syntactical and stylistic problems but the only thing this PR is doing is updating JUCE. Moving forward I will need to sort out this lint issue.

    P.S. This is my first PR to any open source project! It's quite a trivial one, but I look forward to contributing more. Let me know if I did anything wrong and thank you for your patience with my learning in advance.

    The most problem is Scale-block missing. I suppose it's because of '#' cymbol. parameters.keys() skips it or ignores or something like this. And even if it exists, next problem will be:

    At the same time i can turn plugin state to number-style (with Cockos Reaper) and there are much more parameters including '#'-named: image

  • Add pedalboard.io.AudioFile.

    Add pedalboard.io.AudioFile.

    This PR adds:

    • pedalboard.io, a new submodule containing audio input/output classes
    • pedalboard.io.AudioFile, a base class for interfacing with audio files
    • pedalboard.io.ReadableAudioFile, a concrete class for reading audio files
    • pedalboard.io.WriteableAudioFile, a concrete class for writing audio files
    • Tests for the above
    • Examples in the README.

    Questions that may arise from this change:

    • Why are these useful or necessary?
      • Most Python audio reading/writing libraries are single-format (pymad, pyogg, etc), require DLLs to be installed (PySoundFile), or sometimes shell out to FFMPEG (audioread, librosa). Pedalboard (by virtue of JUCE) has the ability to provide high-performance audio reading and writing functionality out-of-the-box without much code, removing the need for third-party dependencies. In tests, this code is up to 20x faster than librosa.load in certain cases (without resampling).
    • Should this be part of Pedalboard, or a separate library?
      • Given that Pedalboard already includes JUCE under the hood, and that adding these classes inflates the binary size by only kilobytes, it seems pragmatic to include these classes here rather than creating a separate library that would itself be a couple MB in size.
    • Why are not all formats supported?
      • This PR wraps JUCE's AudioFormatReader and AudioFormatWriter interfaces, which only support reading and writing a certain set of audio formats out-of-the-box. Notably, Pedalboard already includes libmp3lame, which could be used to create a custom AudioFormatWriter subclass to allow for MP3 file writing out-of-the-box.

  • Any plans to support plugin UIs?

    Any plans to support plugin UIs?

    Neat project, thanks for releasing it as open-source! I have two questions:

    1. Any plans to support plugin UIs? This may not be so relevant for the ML or Content Creation use cases described in your post, but for Creativity it may be useful to be able to open the plugin UI and interact with it directly - for example, to fiddle with parameters more quickly or perform tasks that can only be accomplished in the UI. (May also be relevant for addressing the caveat mentioned at the bottom of the demo notebook, re. DRM-locked plugins.)
    2. Did you happen to look into popsicle? There is some overlap with pedalboard in that it also wraps JUCE in Python, though it uses cppyy rather than pybind11. (And, of course, it exposes the JUCE API directly, rather than the nice Pedalboard interface for running effect chains.)

  • Parallel and Feedback Plug-in Composition?

    Parallel and Feedback Plug-in Composition?

    I'm a newcomer to pedalboard, so apologies if there is already some way to do this!

    Is there any way of chaining plugins in a non sequential way? In particular, having an input pass by two plugins in parallel and then combining them again, or creating some sort of feedback loop with a defined time delay?

    Currently, it seems as though only direct plugins or a sequence (list) of plugins are supported - this limits the potential for creating more interesting plugins.

  • Midi support

    Midi support

    Summary: I've started a basic implementation of MIDI support to get things started

    Problem Pedalboard doesn't currently support plugin instruments because there is no way of sending MIDI to the plugins

    Solution I've added very basic MIDI support using juce::MidiMessageSequence and juce::MidiBuffer.

    Result This is mostly to get the ball rolling with MIDI support, it's definitely not ready for prime-time and haven't rigorously followed the contribution guide. It works for single processors, but not chains because the note off doesn't seem to work for chains. I haven't written any tests because I'm reckless. It's got to where I need it so I'll give it a rest for while. If someone wants to pick up the baton feel free!

    For now I've done the following:

    • Passed juce::MidiMessageSequence to the top-level process methods and based on the block time, passed MidiBuffers to the plugin process methods. This causes some complications with the Chains. My ugly non-working solution is to overload the process method and convert the MidiBuffer back into MidiMessageSequence
    • Added note on and off generation with mido
    • Added a second parameter to the plugin.process and pedalboard process methods that takes midi notes with time offsets in seconds. This should be optional but I couldn't quickly figure out how to do that. If passing in MIDI then the input audio should be optional too I guess.

    • [x] Add a better API for getting device names and input/output details
    • [x] Simplify the stream.plugins API - it should be a "real" list object that supports .append(Plugin), etc.
    • [x] Should the AudioStream API block while audio is being streamed? Would avoid creating a stream, processing audio, and then having it "get lost"
