If you want an audio frequency under linux try xoscope. Price should be
the cost of a download. (345k) Can use several input possibilities
including

[ /dev/dsp
Audio sound recording via /dev/dsp. Two 8-bit analog
channels at 8000 S/s to 44100 S/s. Left and right
audio is connected to X and Y inputs respectively.

EsounD
Shared audio sound via the Enlightened Sound Daemon.
EsounD is auto detected and preferred over /dev/dsp.

ProbeScope / OsziFOX
Radio Shack ProbeScope, Cat. No. 22-310 is also known
as an osziFOX. This handheld probe sends its data
through a serial port. It samples one channel at
6-bits up to 20 MS/s with 128 samples of memory.
Real voltages are labeled in sample ranges from 1
volt to 100 volts.

Bitscope
Bitscope (www.bitscope.com) is a mixed-signal capture
engine which is accessed through a serial port. It
simultaneously samples a digital 8-bit port and two
analog channels at 8 bit resolution at up to 25 MS/s
or more. Bitscope support is currently under development
and not yet fully functional
