You may have to sell a kidney first to buy them.

Propably, but fortunately you can try both free from charges.

Probably only worthwhile if you need to convince yourself or others that it is beyond repair.

I was hopeful, but not really expecting much from this recording. Just too bad I can't go back and do it over.

I don't know what kind of microphone it was, but it wasn't expensive. Simply plugged into a cassette recorder 35 years ago to record the vows and music from a wedding. Before the days of elaborate videographers and equipment......

Thanks for your suggestions, I will give them a try. You've all be very helpful.

Ah, it all starts to come together. An "archival" recording, worth trying to salvage. Begin by working on small sections of the organ part and the vows part until you find settings that work for you.

First, try the High Pass filter with a Rolloff of 12 dB and a Frequency of 100 Hz. That will mitigate the low frequency badness.

Next, go the the Equalizer effect. Click the "Flat" button then switch to "Draw curves" view. Click on the line at about 800 Hz. Click and drag upwards at about 2000 Hz, dragging a point up to about +12 dB. If you don't like what you hear, Undo and try a slightly different curve. When you find one you like, save it. See http://manual.audacityteam.org/index.ph ... ualization

Try both effects on different sections of the recording. You may not need the high-pass filter when the organ is not playing. You may want different Equalization when the organ is not playing.

When you've figured out what parts of the recording need what treatment, start over (Undo back to when you opened the file, or close without saving changes and open again) and apply the effects as and where needed.

Finally, you may want to apply Noise Removal during the vows. The high frequency boost that was applied by the Equalization effect will really bring up the hiss. Don't try to remove the hiss, just try to bring it down a bit. Check this page http://manual.audacityteam.org/index.ph ... se_Removal .

The result will be far from perfect, but may be more listenable than the original.

Good luck.
