HOW DO I REMOVE CRACKLING SOUND FROM CASSETTE RECORDING?

[H Gordon]

Working on an old desk top - no apps running but put Audio to Buffer to 80 and it seems to have sorted the problem for the last tape I have done - lets hope it works for the rest.

Thank you for your help.

What value was "Audio to Buffer" at before?

100

Thanks, that was default value.

Reducing the buffer normally runs the risk of causing dropouts, but sometimes lower settings are required on Mavericks with Audacity.

First of all, you can not to connect the line level output signal from the cassette tape deck to the microphone input connector of your computer (desktop or laptop).
The microphone connector is made to handle a microphone level signal (-57 db). The cassette tape deck has line level signal (-10 db).
Some desktop computer audio cards have an analog audio line level signal connector (for example: Creative SoundBlaster series). You can use it directly.
Normally, laptop computers audio cards don't have one. So, you need an analog to digital USB interface which has a line level signal stereo connector (most of them have one).

This is all true, but this is the Mac board.

Until the advent of the combo input/output, most Macs only had a line-level audio input and no mic input at all. The poster's sample file was not excessively loud and presumably they have a line-level input although they called the input a microphone.
