Code-It-Yourself! Sound Synthesizer #1 - Basic Noises
I would like to do this using my laptop. One method would be creating an MP3 with a a single, fixed-frequency tone This can easily done by audacityopening it with a python library and playing it repeatedly. The second would be playing a sound using the computer built-in speaker.
I'm looking for something similar to QBasic Sound :. PyAudiere is a simple cross-platform solution for the problem:. The site and binary installers for Python 2 debian, windows are available via the wayback machine e.
It is a modified to support Python 3 version of this AskUbuntu answer. The module winsound is included with Python, so there are no external libraries to install, and it should do what you want and not much else.
But: A complete answer to this question should note that although this method will produce a sound, it will not deter mosquitoes. It's already been tested: see here and here. I'm putting my code in here as it helps a programmer gain clarity over how the code works.
Explanation is in the code itself:. Learn more. Python library for playing fixed-frequency sound Ask Question. Asked 10 years, 10 months ago. Active 2 months ago. Viewed 34k times. Adam Matan Adam Matan Be careful with MP3, as it gets its compression from removing frequencies less audible to humans, and the threshold of hearing is typically at 20kHz, not far from your 17kHz. So your fixed-frequency tone, when turned into an MP3, may play a different set of frequencies, or attenuate the one you are after.
You, being a human, should probably not be able to tell the difference. But mosquitos may Thanks a lot. So did it work for the mosquitos??? Active Oldest Votes. Can you tell anything about stability issues? The lest release is 0. A friend of mine shared this link with me to get and install pyaudio: people.
BeepIt's very simple and easy, though is only available for Windows.Audio in Python This page tries to provide a starting point for those who want to work with audio in combination with Python. If you are creating a game, most of what you are looking for may already be included in the many PythonGameLibraries that are available.
If you are looking for podcasts related to Python, go to the PythonAudioMaterial page. Built in modules The Multimedia Services allow for some basic audio functionality in Python. It consists of the following modules: audioop Manipulate raw audio data. AIFF chunks. Beyond the default modules Alternatively, you might want to learn about audio programming in Python.
There is a veritable forest of stuff out there, but here are some good starting points. For a complete overview have a look at PythonInMusic. PyAudiere A high-level audio interface for Python. It uses FFmpeg for decoding and PortAudio for output. It supports gapless playback and high sample rates 96kHz or kHz.
It also has the functionality to calculate the ReplayGain value and do loudness normalization, to calculate the AcoustId fingerprint, to get the metadata via FFmpeg and to calculate a visual representation for a sound file.
FMOD is a popular closed, but free for own use, that is used in many commercial game titles. CategoryDocumentation Audio last edited by JoeHamilton. Unable to edit the page? See the FrontPage for instructions. User Login. A high-level audio interface for Python. Uses ffmpeg for formats other than WAVE. Python bindings for PortAudio audio input and output. Python Audio Tools. Part of a music player. This module provides bindings for the PortAudio library using CFFI and a few convenience functions to play and record NumPy arrays containing audio signals.This Python module provides bindings for the PortAudio library and a few convenience functions to play and record NumPy arrays containing audio signals.
Those are needed for the installation of the Python module and its dependencies. Most systems will have these installed already, but if not, you should install it with your package manager or you can download and install pip and setuptools as described on the pip installation page.
If you happen to have pip but not setuptools, use this command:. It supports CPython 2. Once you have installed the above-mentioned dependencies, you can use pip to download and install the latest release with a single command:. If you want to install it system-wide for all users assuming you have the necessary rightsyou can just drop the --user option.
The PortAudio library is also included in the package and you can get the rest of the dependencies on the same page. Assuming you have a NumPy array named myarray holding audio data with a sampling frequency of fs in the most cases this will be or frames per secondyou can play it back with sounddevice.
This function returns immediately but continues playing the audio signal in the background. You can stop playback with sounddevice. If you know that you will use the same sampling frequency for a while, you can set it as default using sounddevice.
To record audio data from your sound device into a NumPy array, use sounddevice. Again, for repeated use you can set defaults using sounddevice. This function also returns immediately but continues recording in the background. In the meantime, you can run other commands.
If you want to check if the recording is finished, you should use sounddevice. If the recording was already finished, this returns immediately; if not, it waits and returns as soon as the recording is finished. By default, the recorded array has the data type 'float32' see sounddevice. To play back an array and record at the same time, use sounddevice.
The number of output channels is obtained from myarraybut the number of input channels still has to be specified. In this case the number of output channels is still taken from myarray which may or may not have 2 channelsbut the number of input channels is taken from sounddevice.
Use sounddevice.As a Data Scientist you never know the upcoming stuffs. The amazing thing of this profession is that you may have to deal with different kind of data formats. Some time it could be textimages or Audio. Yes It could be an audio as well. As a Data Scientist I did not found so many articles on Audio analysis and process library in python. I have documented all my findings this article.
Lets start —. This Python module is really good in Audio Processing stuffs like classification. It supports feature engineering operations for supervised and unsupervised learning stuffs. It helps to perform various common task in sound processing with python. For example -slicing the soundconcatenating the sound etc. I think you should check it out. TimeSide —.
Top 5 Audio Analysis Library for Python : Must for Data Scientist
It is a well design python framework for Audio Analysis. It is more popular for audio processing in python with web. This is really one of the great python module for audio processing specially tagging ,and meta data extraction. Mutagen also provide command line interface. Truely speaking! To provide a particular name at this place will be injustice to others Python Audio Processing and Analysis Library. Hence I have decide to create a bucket for this. Here are a list of some more interesting Python Libraries for Audio Processing —.
Audio processing is harder with Machine Learning. Actually before sending directly to Machine Learning Platform so many hidden tasks. Which are quite time taking but seems small. Like we have to load the sound. The imported or loaded audio sample may be of some different format. We have to first convert them into the required one.
Now the above mention Library comes to the role. Few of them are coming with such features of format conversion. Now once it is converted into the required formatwe have to perform the preprocessing like noise removal and all.
After it the last and the most important step comes where we have to extract the feature from the audio sample.The winsound module provides access to the basic sound-playing machinery provided by Windows platforms.
It includes functions and several constants. The frequency parameter specifies frequency, in hertz, of the sound, and must be in the range 37 through 32, The duration parameter specifies the number of milliseconds the sound should last. If the system is not able to beep the speaker, RuntimeError is raised. The sound parameter may be a filename, a system sound alias, audio data as a bytes-like objector None. Its interpretation depends on the value of flagswhich can be a bitwise ORed combination of the constants described below.
If the sound parameter is Noneany currently playing waveform sound is stopped. If the system indicates an error, RuntimeError is raised. This plays a sound as specified in the registry. The sound parameter is the name of a WAV file. The sound parameter is a sound association name from the registry. If no default sound is registered, raise RuntimeError.
PlaySound name. Play the sound repeatedly. Play the SystemDefault sound. Play the SystemExclamation sound. Play the SystemHand sound. Play the SystemQuestion sound. Unix Specific Services. PlaySound "SystemExit"winsound. Note This flag is not supported on modern Windows platforms.

Created using Sphinx 2.Released: Nov 25, View statistics for this project via Libraries. Tags audio, libsndfile. SoundFile can read and write sound files. SoundFile represents audio data as NumPy arrays. SoundFile has evolved rapidly during the last few releases.
Most notably, we changed the import name from import pysoundfile to import soundfile in 0. Also, the order of arguments of the write function changed from write data, file, The old ctype arguments still work, but are now officially deprecated. In a modern Python, you can use pip install soundfile to download and install the latest release of SoundFile and its dependencies. On Windows and OS X, this will also install the library libsndfile.
If you are running on an unusual platform or if you are using an older version of Python, you might need to install NumPy and CFFI separately, for example using the Anaconda package manager or the Unofficial Windows Binaries for Python Extension Packages. Data can be written to the file using soundfile. Sound files can also be read in short, optionally overlapping blocks with soundfile. For example, this calculates the signal level for each block of a long file:.
Sound files can also be opened as soundfile. SoundFile objects.
Play sound in Python
Every SoundFile has a specific sample rate, data format and a set number of channels. If a file is opened, it is kept open for as long as the SoundFile object exists.
The file closes when the object is garbage collected, but you should use the soundfile. All data access uses frames as index. A frame is one discrete time-step in the sound file.
Every frame contains as many samples as there are channels in the file. Pysoundfile can usually auto-detect the file type of sound files. This is not possible for RAW files, though:. You can write RAW files in a similar way, but be advised that in most cases, a more expressive format is better and should be used instead. Note that the above example only works with Python 3. For Python 2. Writing to OGG files can result in empty files with certain versions of libsndfile.

Alternatively, you can download or clone the repository and use pip to handle dependencies:. By calling pip list you should see librosa now as an installed package:.
Note that soundfile does not currently support MP3, which will cause librosa to fall back on the audioread library. If you're using conda to install librosa, then most audio coding dependencies except MP3 will be handled automatically. If you're using pip on a Linux environment, you may need to install libsndfile manually. Please refer to the SoundFile installation documentation for details.
To fuel audioread with more audio-decoding power e. Note that on some platforms, audioread needs at least one of the programs to work properly. If you are using the library for your work, for the sake of reproducibility, please cite the version you used as indexed at Zenodo:. If you wish to cite librosa for its design, motivation etc.
