Interesting solution! I'm surprised it can tell the diff between 6000 and 6001 hz, most audio devices run at fixed frequencies and most players don't bother correcting. Using your much-beloved sox utility on a fixed-rate raw file might give you more reliable and portable control -- resample it to one rate and force it to output at another rate.
:cool: after installing solaris 10 5/08/09 directory the computer rebooting then the massage "out of frequency" appear.i want a solution first

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)

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)

RTII(4) BSD Kernel Interfaces Manual RTII(4)NAME
rtii -- AIMS Lab Radiotrack II FM radio device driver
SYNOPSIS
option RADIO_TEA5759
rtii0 at isa? port 0x20c
rtii1 at isa? port 0x30c
radio* at rtii0
DESCRIPTION
The rtii driver provides support for the AIMS Lab Radiotrack II FM radio tuners.
The Radiotrack II 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 Radiotrack II 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 either 0x20c or 0x30c.
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.

The rtii device driver appeared in OpenBSD 3.0 and NetBSD 1.6.
