Manipulating Audio with Python: Play Record and Convert Files

Audio Files: How to Play and Record Audio Using Python

Music and sound are deeply woven into our lives. From the ambient sounds of nature to the therapeutic sounds of serene music, audio plays a huge role in our sense of well-being.

No wonder, then, that there are many ways to manipulate and create audio with tools like Python. In this article, we’ll take a look at the different libraries and techniques used to play and record audio files in Python.

Playing Audio Files

Playing audio in Python is a fun and enjoyable process. There are many libraries that you can use to play audio files.

Here are some of the most popular ones:

1. Playsound

Playsound is a simple library that you can use to play audio files.

It supports WAV, MP3, OGG, and FLAC files. The syntax is straightforward.

All you need to do is import the library and call the playsound function with the audio file as an argument. 2.

Simpleaudio

Simpleaudio is another popular library for playing audio files in Python. It supports WAV files and NumPy arrays as input.

Simpleaudio can play audio files asynchronously or synchronously. The library also provides an easy way to read and write audio data.

3. Winsound

Winsound is a library that is built-in to Windows systems.

It is used to play system sounds, but it also supports WAV files and can be used to play music. The syntax is almost similar to Playsound.

You just import the library and call the winsound.PlaySound method. 4.

Python-sounddevice

Python-sounddevice is a cross-platform library that can be used to play and record audio. The library is built on top of PortAudio, which is a powerful audio library that supports many audio interfaces.

Python-sounddevice supports NumPy arrays as input and provides an easy way to manipulate audio data. 5.

Pydub

Pydub is a library that supports many audio types. It is built on top of ffmpeg, which is a popular audio/video library.

You can use Pydub to split, concatenate, and adjust audio files. The library also provides a simple way to export audio files.

Recording Audio Files

Recording audio in Python is quite different from playing audio. Here are some of the best libraries for recording audio:

1.

Python-sounddevice

Python-sounddevice is not only great for playing audio but also for recording audio. It supports NumPy arrays as input and provides a simple way to manipulate audio data.

All you need to do is import the library and call the sd.rec() method with the parameters that you prefer. 2.

Pyaudio

Pyaudio is a powerful library for recording audio. It supports bytes objects as input and provides a lot of settings to customize how the recording is done.

Pyaudio is a cross-platform library that can be used in combination with other libraries like NumPy.

Conclusion

Python is a robust programming language that can do just about anything, including playing and recording audio files. With the libraries and techniques we’ve discussed, you can easily incorporate audio into your Python projects.

Whether you’re creating games, analyzing sound data for research or simply enjoying music, the possibilities are endless. So why not try playing or recording audio files with Python today?

Saving and Converting Audio

The third part of manipulating audio with Python is saving and converting sound files. In this section, well check out several libraries that you can use to save and convert audio files.

Libraries for

Saving and Converting Audio

1. Wavio

Wavio is a library that allows you to write NumPy arrays to WAV files and read WAV files to NumPy arrays.

The library provides a simple interface to read or write NumPy data to WAV files, making it easy to save audio data. Wavio uses simple algorithms to handle WAV files, allowing for easy implementation of audio processing algorithms.

2. Soundfile

Soundfile is a library that provides access to audio files in many different formats.

Soundfile uses libsndfile, which is a powerful audio tool used to read and write many different audio file formats, including FLAC and AIFF. Soundfile is a powerful library that allows you to access audio files with many different file formats, making it an essential tool for audio data manipulation.

Comparison of Audio Libraries

When it comes to choosing the right library for working with audio in Python, you want to consider several factors: ease of use, features, speed, and file format support. Heres a table comparing some of the most popular audio libraries in Python:

| Library | Ease of Use | Features | Speed | File Format Support |

| —————- | ———–| ————————–| ———| ———————-|

| Playsound | Easy | Simple playback | Fast | WAV, MP3, OGG, FLAC |

| Simpleaudio | Moderate | Playback, data I/O, resamp | Fast | WAV |

| Winsound | Easy | Simple playback | Fast | WAV |

| python-sounddevice| Moderate | Advanced playback, recording | Fast | WAV, IO, AIFF |

| Pydub | Moderate | Editing, file format | Moderate| Many |

| Wavio | Easy | NumPy to WAV, WAV to NumPy | Fast | WAV |

| Soundfile | Moderate | Many file formats, metadata| Moderate| Many |

From the table, you can see that each library has its unique strengths.

If you want simple playback, Playsound or Winsound is a good choice. For more advanced playback and recording, Python-sounddevice is the best option.

Pydub is your go-to if you require audio editing and file format support. If you need to convert file formats and access metadata, Soundfile is your best bet.

In conclusion, choosing the right library for sound file manipulation depends on your use case and the specific features you require. Thankfully, there are many libraries available to make playing, recording, saving, and converting sound files in Python a breeze.

Playing and Recording Sound in Python
