A Function To Create A 1 Second Sinewave WAVE Beep File. (Python)

2014-11-23T19:24:46-08:00

Python recipe 578971 by Barry Walker (amiga, apple, audio, beep, error_beep, error_sound, e_uae, linux, sinewave, sound, wav, wave, windows, winuae).

sinebeep.py

Creating an audio file called...

beep.wav

...that can be played using almost ANY audio player available.

This simple snippet of code generates a 1 second sinewave WAVE file. It IS saved inside the CURRENT drawer so that you can find it... ;o)

This works on:- Classic stock AMIGA A1200, using Python 1.4.0. WinUAE and E-UAE, AmigaOS 3.0.x using Python 1.4.0 to 2.0.1. Windows, to at least 7, using Python 2.0.1 to 3.3.2. Various Linux flavours using Python 2.4.6 to 3.2.2. Apple OSX 10.7.x and above using Python 2.5.6 to 3.4.1.

The file size is 8044 bytes and _IF_ you need to it can be palyed directly without a player on some Linux flavours that have the /dev/dsp device. It is an 8 bit, unsigned integer, mono, 8000Hz sampling speed 8000 byte RAW file with the WAVE header added.

It will still work with PulseAudio and OSS using...

cat /full/path/to/beep.wav > /dev/dsp

...but with a momenatry click due to the 44 header bytes; but hey it is a beep alternative...

A Bash Beep Command For OSX 10.7+... (Bash)

2014-02-27T19:36:17-08:00

Bash recipe 578837 by Barry Walker (apple, audio, bash, beep, error_beep, error_sound, linux, macbook_pro, sound).

This small bash script generates an 8044 byte 1KHz sinewave wave file and immediately plays it. The file created is a _pure_ sinewave and lasts for 1 second. It uses the default "afplay" command to run the generated file.

It was designed around an Apple Macbook Pro but using "aplay" it might even work on other *nix flavours from the command line. I have not bothered to try it as this was purely for my MB Pro.

The wave file can be found as "/tmp/sinewave.wav" during the working session(s) and can be saved anywhere of your choice.

Enjoy...

A FUN Bash Shell Bomb-Out Error Sound... (Bash)

2013-07-14T19:31:13-07:00

Bash recipe 578605 by Barry Walker (apple, audio, bash, error_beep, error_sound, linux, macbook_pro, sound, sound_exchange, sox).

Do you remember the Bomb-Out icon(s) that appeared on some computers' SW and HW many years ago...

Well this is a matching sound to go with it and can be used as a critical error sound.

It sounds like a bomb being dropped from an aeroplane and is purely a shell sript only.

It is set up to run SOund eXchange, SOX, but just by editing the code "/dev/dsp" can be used instead.

Read the code for more informastion.

Clear screen and beep for various platforms. (Python)

2011-02-26T14:26:02-08:00

Python recipe 577588 by Barry Walker (amiga, audio, beep, clearscreen, display, error_beep, error_sound, e_uae, linux, screenclear, sound, windows, winuae).

This little module gives a clear screen and beep for the classic AMIGA, WinUAE, Windows and Linux all in CLI/Command-Prompt/Terminal mode.

It works from Python 1.4.x to 2.7.x; talk about backwards compatibility... ;oD With very little modification it will work on Python 3.x.x easily.)

See the file clsbeep.py attached for more information.

it is saved as clsbeep.py and placed into the Python - Lib drawer or where-ever the modules are located and called as a module:-

>>> import clsbeep

Its usage is:-

clsbeep.cls() and clears the screen. clsbeep.beep() and creates an error beep. clsbeep.both() creates an error beep first then clears the screen.

It is Public Domain and if you modify it to suit other platforms please let me have a copy of your code... :)
