A command-line musical alarm clock (Python)

2016-12-30T19:06:32-08:00

Python recipe 580739 by Vasudev Ram (alarm, audio, clock, multimedia, music, playsound, python, time, utilities, utility).

This is a simple musical alarm clock in Python. You pass a command-line argument specifying the time in minutes after which the alarm should go off. When that time arrives, it plays a musical sound.

Simple audio with ctypes and SDL also for Tkinter (Python)

2015-08-17T18:54:17-07:00

Python recipe 579070 by Jiri Justra (audio, sdl, sdl_mixer, tkinter). Revision 3.

I've needed just to play audio in my Tkinter application, but it seems there is no easy way to do this, so I have made this simple code. It is small ctypes wrapper around SDL_mixer.

It should work for Win and *nix also .. I've tested it on ubuntu-14.04.3-desktop-i386

Not Quite So Simple QuickTime Player, Python Audio Capture. (Python)

2014-11-08T19:10:58-08:00

Python recipe 578960 by Barry Walker (apple, audio, audio_capture, capture, macbook_pro, maccbook_pro, sample, signal_capture).

Not Quite So Simple QuickTime Player, Python Audio Capture.

This DEMO code captures a function to generate a user 5 second Audio sample in Apple *.aifc format. It is then converted to DC quailty *.WAV format.

It uses default shell system files to do the task.

An AppleScript is created to do the sample but due to the limitations of QT Player there is a 1.5 second delay to allow QuickTine Player to start up. It is not entirely quiet but unobtrusive enough as to be like quiet mode...

This is again a means a signal capture for an AudioScope without the need for special tools or installs.

Read the code for more information.

IMPORTANT!!! This DEMO WILL delete all *.aifc files inside the default $HOME/Movies directory, so be aware.

A simple ALSA one is on its way too...

It actually works on Python 3.4.1 but I have no idea if it works below Python 2.5.6...

Simple Audio Capture For Windows... (Python)

2014-10-17T14:39:16-07:00

Python recipe 578952 by Barry Walker (audio, audio_capture, capture, sample, signal_capture, windows).

This snippet will capture from approximately 1 second to nearly 10000 hours of audio silently using Windows SoundRecorder.exe and save automatically to a file named SAMPLE.WAV in the C:\Windows\Temp\ folder/drawer/directory. It is 16 bit signed integer depth, stereo and sampled at 44100 Hz. This is for Python 2.0.1 to 3.3.2, (my latest version).

Enjoy finding simple solutions to very difficult problems...

(An OSX version is on its way too...)

Recursive Multimedia (audio, video) M3U Playlist Generator (Python)

2014-02-08T01:03:36-08:00

Python recipe 578771 by Mano Bastardo (audio, ffmpeg, generate, m3u, mulitmedia, os, playlist, python, system, video). Revision 9.

Generate an m3u playlist searching recursively for multimedia files (video or audio) in the given directory. Information from ID3 tags will be extracted for audio files with FFmpeg available.

How to stream an mp3 file using vlc.py, with a simple TKinter GUI. (Python)

2013-06-09T12:52:30-07:00

Python recipe 578556 by Anton Vredegoor (audio, streaming, tkinter, vlc).

This script can be used to stream an existing mp3 file to multiple computers. It has a simple Tkinter GUI with only one button to start/stop the stream, and a slider to indicate or change the position.

Bash Script For An Oscilloscope... (Bash)

2013-06-19T19:06:50-07:00

Bash recipe 578570 by Barry Walker (anim, audio, audioscope, bash, oscilloscope, scope, script, sound_exchange, sox, terminal).

This code is the latest as of 19-06-2013. It is an AudioScope designed around a Macbook Pro 13" of which only has ONE microphone input. It works under Linux variants too. Read the code for much more info.

It was my way of learning Bash scripting.

It is resident here at this site:-

http://www.unix.com/shell-programming-scripting/212939-start-simple-audio-scope-shell-script.html

It started off as a fun idea and is now becoming a very serious project.

As it stands this is fully working but it is uncalibrated and this is where it will stay on this site.

As the above site is the host then all future uploads will be there...

To do list...

DC input. [1] DC polarity. [1] 2 more Internal sync modes. External triggering. Zoom facility - if possible in text mode. Vertical calibration. [2] Frequency measurement. {3] (Others.)

[1] I have simple HW built as an idea but yet to prove it... [2] Preliminary HW built but not yet used. Calibration SW and circuit(s) to be built into script as it progresses. [3] I already have a working script but not completely satisfied at it at this point...

I am noing to say much else except that it has already been given a 5 star rating on the above UNIX site...

As it stands this code is entirely Public Domian and you may do with it as you please...

Enjoy something completely different using Bash scripting...

Finally the code defaults to a DEMO mode which requires no HW access at all but everything is still functional...

__Thoroughly__ read the code for more information...

As a circuit is inside the script then it is best viewed in plan text mode.

Using vlc.py to record an mp3 and save a cue file (Python)

2011-07-25T15:55:38-07:00

Python recipe 577802 by Anton Vredegoor (audio, recording). Revision 2.

This is an example of how to use vlc.py . It records an mp3 file from an online audio stream, using the track announcements to write an accompanying cue file.

DUAL 4 Bit Vertical Coloured Analogue Bar Graph Generator DEMO... (Python)

2011-05-04T17:58:08-07:00

Python recipe 577685 by Barry Walker (analogue, anim, audio, bargraph, color, colour, demo, display, linux).

This is a two channel version of the "Four Bit Vertical Coloured Analogue Bar Graph Generator DEMO...".

These are DUAL LED style "VU" meters in the vertical plane...

This is for standard Python 3.x.x.

It has different overload beeps for each channel, and has all the unwanted code has been removed.

It demonstrates how to obtain multichannel ability, (it is possible to add more channels).

Seven Bit Colored Analogue Bar Graph Generator DEMO... (Python)

2011-03-17T22:14:52-07:00

Python recipe 577612 by Barry Walker (analogue, anim, audio, bargraph, color, colour, demo, display, linux). Revision 3.

..For STANDARD Python 2.6 and above...

This code will display a horizontal full colour analogue "VU" style meter. It displays green for normal, yellow for warning and red for danger with a critical error beep near the end of full scale, at value 120+.

This version is for Python 2.6 and above and only for the Linux, (*nix?), platform.

It is an "at a glance" display that is in colour rather than having to read say a digitally generated number.

A Python 3.x version can be found here:-

http://www.linuxformat.com/forums/viewtopic.php?t=13443

This has uses "for at a glance" voltmeters, ammeters, data-loggers, anemometers etc, etc...

Watch for wordwrapping etc...

Four Bit Vertical Coloured Analogue Bar Graph Generator DEMO... (Python)

2011-04-23T20:50:55-07:00

Python recipe 577675 by Barry Walker (analogue, anim, audio, bargraph, color, colour, demo, display, linux).

This is a(n) LED style "VU" meter in the vertical plane instead of the horizontal one in the recipe below:-

http://code.activestate.com/recipes/577612-seven-bit-colored-analogue-bar-graph-generator-dem/?in=lang-python

It is another "AT A GLANCE" display with an overload error beep too.

This is for Linux only and tested on Python 2.6.x although it should work on earlier 2.x.x versions.

A Python 3.x.x version can be found here:-

Simple analogue anim and digital voltmeter with alarm DEMO... (Python)

2011-03-04T19:47:37-08:00

Python recipe 577596 by Barry Walker (amiga, analogue, anim, audio, demo, digital, display, e_uae, linux, voltmeter, windows, winuae).

I needed a simple standard Python analogue and digital display along with an overload beep when used as a basic voltmeter.

Analogue readout, for quick glance. Digital readout, for better accuracy. Beep, to warn me of impending doom... ;o)

This was my starter code and works from Python 1.4.x to 2.7.x on MINIMUM platforms, AMIGA A1200, MS Windows ME and Knoppix 5.1.1. It is a stand alone program and the easiest way to start it is to import it as though it is a module.

(I DO have a Python 3.x.x version too and WILL be uploaded here in the future.)

Although this is a DEMO it did access, (home built), HW from various ports on differing platforms.

This module IS needed for it to work:-

http://code.activestate.com/recipes/577588-clear-screen-and-beep-for-various-platforms/?in=lang-python

These simple HW access modes using standard Python code WILL be released in the future.

This DEMO is released as Public Domain and you may modify it as you please...
