Hello. I have the audio for an old Without Toil course in mp3 format. It is all from the
original records so there are only 6 total tracks for the entire course. I spent some time playing in audacity to reduce the background noise from the record player. It sounds a ton better and cleaner now. Sometimes the first words on sentences "hits" kind of hard and sounds like a burst of bass. No idea how to rid the track of that. Any tips? I know little of audio recording and formatting. But if it is possible with Audacity, I will give any ideas a try. Beyond wanting to fix that, does anyone know if it is possible to set a bunch of "cut" spots in Audacity and then have it form into a bunch of individual files? Otherwise I'd have to measure out and cut-paste all 140 lessons. That seems incredibly time consuming, so I figured I'd ask if anyone knew a more efficient way first. Thanks, all. 1 person has voted this message useful | |

I don't have a clue about you first question.
But I split my files with audacity. I just mark a part and export/extract it from the file. Then you have the possibily to save it as mp3 or something else. It is manuelly and I'm not sure if you mean the same with cut-paste. After a while you will "see" where a lesson starts/ends and then it is going faster. 2 persons have voted this message useful | |

Thanks,Mareike! I didn't think to use export selection. I was going to try to cut and
paste each lesson into a new window, haha. This way seems much faster! I think I will do all the splitting tonight and then have a "master" track that I can do a batch edit to later if I find the audio to be too annoying. Thanks for the tip! 1 person has voted this message useful | |

Audacity's "Apply Chain" is another handy feature that I didn't know about right away, but now it's the most
common way I apply effects to audio. You "Edit Chain" first to create it. The chain I use the most and for almost everything: TruncateSilence Compressor ExportMP# -END- Another chain when the audio originates from CD is wav2mp3 is just: Compressor ExportMP# -END- When the audio is even, but not using the full sound spectrum, E.G., a professional recording that doesn't fill up the visual graph, I use a chain I call "Normalize". Normalize Compressor ExportMP3 -End- Edited by luke on 27 September 2014 at 12:27pm 1 person has voted this message useful | |

If the cuts are awkward, e.g. not on a silence, for example sometimes they play music between speaking tracks, then you can manually mark them (label) then export multiple via label. If there is a silence then you can use silence finder to label for you then export.
One thing which might annoy you is by default audacity prompts you to review meta data when exporting, you can turn this off in the preferences. Can't remember the exact setting, but Google is your friend. 2 persons have voted this message useful |
