I tried this on cygwin and I had to replace
Code:
afplay /tmp/sweep.wav

with
Code:
cat /tmp/sweep.wav > /dev/dsp

and guess what??? it worked
I heard the sound
Can you please share more about creating .wav files and with different frequencies...also suggest a good book on this
Thanks

Error with Audio Conversion Bash Script

Good evening, I'm currently working on a BASH script to convert audio between file formats and I've come across a snag. At the beginning of the script, I'm having the system check to see if any files with the .m4a extension exist in the directory, and if so, it runs the script. If there are no... (1 Reply)

IP Ping Sweep

I put this together to search for unused IP addresses on a router. It's run as a Bash Command on OSX 10.9. Basically the user inputs the router address' IP range to sweep. 'jot' spits out a list of IP addresses based on that input and each one of those gets pinged. The output looks like this (tab... (4 Replies)

A simple variable frequency sinewave audio generator.

Hi all... Well I have not been inactive but working out how to make OSX 10.14.x command line audio player have a variable sample rate. This is a back door as afplay does not have a sample rate flag unlike aplay for ALSA, in Linux flavours. This is a DEMO only but a derivative of it will... (2 Replies)

MIXER(1)						  The Canonical Csound Reference						  MIXER(1)

NAME
mixer - Mixes together a number of soundfiles. . DESCRIPTION
Mixes together a number of soundfiles, starting at different times and with individual channel selection from the input files. SYNTAX
mixer [OPTIONS ... ] infile [[OPTIONS... ] infile] ... INITIALIZATION
Flags: o -A = Generate an AIFF output file. o -W = Generate an WAV output file. o -h = Generate an output file with no header. o -c = Generate 8-bit signed_char sound samples. o -a = Generate alaw sound samples. o -u = Generate ulaw sound samples. o -s = Generate short integer sound samples. o -l = Generate long (32 bit) integer sound samples. o -f = Generate floating point samples. o -F arg = Specifies the gain to be applied to the following input file. If arg is a floating point number that gain is applied uniformly to the input. Alternatively it could be a file name which specifies a breakpoint file for varying the gain for different periods. o -S integer = Indicate at which sample to start to mix in the next input file. o -T fpnum = Indicate at which time (in seconds) to start to mix in the next input file. o -1 = Mix in channel 1 from next sound file. o -2 = Mix in channel 2 from next sound file. o -3 = Mix in channel 3 from next sound file. o -4 = Mix in channel 4 from next sound file. o -^ intx inty = Mix in channel x from next sound file as channel y in the output. o -v = Verbose mode. o -R = Continually rewrite the header while writing soundfile (WAV/AIFF). o -H integer = Show a "heart-beat" to indicate progress, in style 1, 2 or 3. o -N = Alert call (usually ringing the bell) when finished. o -o fname = output file name (default: test.wav) EXAMPLES
The default values are mixer -s -otest -F 1.0 -S 0 For example mixer -F 0.96 in1.wav -S 300 -2 in2.aiff -S 300 -^4 1 in3.wav -o out.wav This creates a new sound file with a constant gain of 0.96 from in1.wav with the second channel of in2.aiff mixed in after 300 samples and channel 4 of in3.wav outpout as channel 1 after 300 samples.
