A fourth mic, which is part of a cheap headset (small knob on a flexible stalk) works fine with the W7 desktop!!! (What kind of mic is that likely to be, please? Difficult to say for certain, but it is quite likely that is an electret microphone . These types of microphone require a low voltage sup...

If you have Realtek HD audio manager installed you have just about complete control of all the input and output ports on the rear and front of your PC case. Sadly that is not always the case. I have seen radically different interfaces for controlling Realtek HD audio. Some have been as you say, eas...

The third sample (partoftrack1.wav) also has DC offset. Again use DC offset correction before anything else. Looking at the noise in Plot Spectrum (after DC offset correction) spikes can be seen at 50, 100, 150, 250, 300, ..... These correspond to the buzz that is clearly evident (see here for the c...

The first sample (partoftrack2volumeup.wav) has been recorded too loud. Zoom in close and you can see how some of the peaks have been "clipped" off flat. firsttrack000.png The best thing to do with this recording is to delete it and start again. ;) The second sample (partoftrack2.wav) has ...

OMFG, THANK YOU! This is exactly what a limiter should be! :shock: :) Thanks for testing it - I'm quite pleased with it myself ;) If you have the time, could you post a brief "review" on the page where I've uploaded it . Just a brief note of how you used it, whether it does what you thoug...

I think that we will need to see / hear what you have. I presume that the "beats" are quite obvious by listening? Open the file in Audacity and select about 3 to 4 seconds that contain some of these "beats". From the File menu, choose "Export Selection" and choose "...

Post moved to the Audacity 1.3.x part of the forum. I selected Microsoft Sound Mapper but when I record, the input (the song) is not recorded, only a background noise (of microsphone) is recorded If you want to record sounds that are playing on your computer you need to set the Audacity recording in...

The wavelength (length of a single cycle) of a periodic (repeating) wave is 1/frequency. For a frequency of 8363 Hz, the wavelength will be 0.000119574 seconds. For greater accuracy this can be represented in samples (the smallest time unit in digital audio). by multiplying by the sample rate. For a...

That's going to be very tough to clean up. Here's the Spectrum View of the track: firsttrack001.png Those red horizontal lines that continue throughout the track are the individual frequencies that make up the buzz. To remove the buzz, all of those frequencies needs to be filtered out. This can be d...
