Now it comes as a surprise to many people when I tell them that generating an audio waveform is extremely simple. One needs to have basic understanding on how audio signals work and basic python programming to generate any audio wave form. This post will show you exactly how. Link to code : GitHub. You can find a list of other waveforms that can be generated using SciPy here. Check this reddit post if you really want to have one. And this is a problem if you want to make larger audio files.
Feel free to play around with the code to change it to other formats.Ecoatm promo code iphone xr
Like Liked by 1 person. Like Like. The code shown here does not generate wav files. The wav file format is not just a collection of samples. It is a collection of chunks of data. One of these chunks contains samples. You are right Nicolas, it does not generate a wav file. But it does generate a raw audio data file which contains the information.

It requires one argument - the path to the file with the sound you'd like to play. This may be a local file, or a URL. There's an optional second argument, block, which is set to True by default. Setting it to False makes the function run asynchronously. On Windows, uses windll. Other file formats may work as well. On Linux, uses GStreamer. Known to work on Ubuntu Support for the block argument is currently not implemented. I've only tested playsound it with Python 2. Skip to content.

Podcast Programming tutorials can be a real drag. Featured on Meta.Many of the applications out there records your voice as well as playing sounds, if you want to do that as well, then you came into the right place, in this tutorial, we will be using different Python libraries to play and record audio in Python.
Let's install the required libraries for this tutorial:. First, we gonna start with the most straightforward module here, playsound :. Yes, that's it required for this module, it is basically a pure Python, cross platform, single function module.Samsung s7 edge
The documentation says that WAV and MP3 extensions are known to work, and it may work for other formats as well. Another alternative is to use Pydub library:. Note : You need ffmpeg installed in your machine in order to use AudioSegment. Pydub is quite a popular library, as it isn't only for playing sound, you can use it for different purposes, such as converting audio files, slicing audio, boosting or reducing volume, and much more, check their repository for more information.
If you wish to play audio using PyAudio, check this link. To record voice, we gonna use PyAudio library, as it is the most convenient approach:. The above code basically intializes the PyAudio object, and then we open up a stream object that allow us to record from the microphone using stream.
After we finish recording, we use the built-in wave module to write that WAV audio file into the disk. Alright, in this tutorial, you learned how you can play audio files using playsoundPydub and PyAudio libraries as well as recording voice using PyAudio.
A great challenge for you, is to combine this with a screen recorderand you'll come up with a Python tool that records your voice and screen simultaneously, you will need to use a thread that records audio, and another one for the screen recorder, good luck with that!

I read this link solutions and can't solve my problem with playing wave file! You can use PyAudio. An example here on my Linux it works:.
Your wav is probably 8k. So when pygame plays it, it plays roughly twice as fast. So specify your wav frequency in the init. Pyglet has some problems correctly reading RIFF headers. If you have a very basic wav file with exactly a 16 byte fmt block with no other information in the fmt chunk like 'fact' datait works. But it makes no provision for additional data in the chunks, so it's really not adhering to the RIFF interface specification.

Read and write WAV files using Python (wave)
PyAudio is inspired by:. To use PyAudio, first instantiate PyAudio using pyaudio. PyAudio 1which sets up the portaudio system. To record or play audio, open a stream on the desired device with the desired audio parameters using pyaudio. This sets up a pyaudio.
Stream to play or record audio. Play audio by writing audio data to the stream using pyaudio. Use pyaudio. Finally, terminate the portaudio session using pyaudio. Note that PyAudio calls the callback function in a separate thread. Start processing the audio stream using pyaudio. A PortAudio Sample Format constant.
Close a stream. Typically use Stream. Return a dictionary containing the default Host API parameters. Return the default input Device parameters as a dictionary. Return the default output Device parameters as a dictionary. Returns the size in bytes for the specified sample format a PortAudio Sample Format constant. Check to see if specified device configuration is supported. Returns True if the configuration is supported; throws a ValueError exception otherwise.
Open a new stream.
See constructor for Stream.The wave module provides a convenient interface to the WAV sound format. The wave module defines the following function and exception:. If file is a string, open the file by that name, otherwise treat it as a seekable file-like object. If mode is omitted and a file-like object is passed as filefile. A synonym for openmaintained for backwards compatibility. An error raised when something is impossible because it violates the WAV specification or hits an implementation deficiency.
Close the stream if it was opened by waveand make the instance unusable. This is called automatically on object collection. Returns number of audio channels 1 for mono, 2 for stereo.

Returns compression type 'NONE' is the only supported type. Human-readable version of getcomptype. Usually 'not compressed' parallels 'NONE'. Make sure nframes is correct, and close the file if it was opened by wave. This method is called upon object collection.
Set the compression type and description. At the moment, only compression type NONE is supported, meaning no compression. Sets all parameters.

Note that it is invalid to set any parameters after calling writeframes or writeframesrawand any attempt to do so will raise wave. The wave module defines the following function and exception: wave.
