Files are not needed if you are using SOX and piping.
An ultra simple string piped into sox without the need for files at all...
But I am NOT using SOX here but the very, very limited afplay audio player for OSX. afplay cannot replay raw files only a few basic formats of which .WAV is one.
Results:-
Just change the sample speed inside SOX from 8000 to anything you like within limits.

I'm trying to record audio using Audacity 2.0.5 installed from SlackBuilds. My system is 64-bit Slackware 14.1 and a sound card is Intel HD Audio. I didn't change my sound system to OSS. (Default sound system in Slackware 14.1 is ALSA, isn't it?) First, I set Internal Microphone slider in KMix... (2 Replies)
This is a small program as a tester for a basic sweep generator for bandwidth testing of AudioScope.sh.
This DEMO is only capable of 4KHz down to about 85Hz and back due to the low bit rate, but it is proof of concept for a much wider variant using a much higher bit rate.
The file generated... (4 Replies)
Ok guys, gals and geeks...
As from today I am starting to learn awk in earnest doing something totally different.
I am going to create a pseudo-Audio_Function Generator centred around OSX 10.11.x minimum. The code below is a tester to see what the possibilities are.

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)

SF2R(4) BSD Kernel Interfaces Manual SF2R(4)NAME
sf2r -- SoundForte RadioLink SF16-FMR2 FM radio device driver
SYNOPSIS
option RADIO_TEA5759
sf2r0 at isa? port 0x384
radio* at sf2r0
DESCRIPTION
The sf2r driver provides support for the SF16-FMR2 FM radio tuners.
The SF16-FMR2 is a stereo FM tuner that allows to tune in the range 87.5 - 108.0 MHz, report signal status on the current frequency, force
audio output to mono, perform hardware signal search, and has an internal AFC.
The SF16-FMR2 cards take only one I/O port. The I/O port is set by the driver to the value specified in the configuration file and must be
0x384.
Philips Semiconductors released two almost identical chips TEA5757 and TEA5759. The TEA5757 is used in FM-standards in which the local
oscillator frequency is above the radio frequency (e.g. European and American standards). The TEA5759 is the version in which the oscillator
frequency is below the radio frequency (e.g. Japanese standards). The option RADIO_TEA5759 changes the algorithm of frequency calculation
for the TEA5757 based cards to conform with the Japanese standards.
SEE ALSO isa(4), radio(4)HISTORY
The sf2r device driver appeared in OpenBSD 3.0 and NetBSD 1.6.
AUTHORS
The sf2r driver was written by Vladimir Popov and Maxim Tsyplakov. The man page was written by Vladimir Popov.
BUGS
MediaForte made two variants of the SF16-FMR2 cards, the first one has an internal amplifier of the output sound, the second one does not
have such an amplifier. The current driver supports only the second variant.
