I am getting a little better with #Audacity and audio editing since starting to podcast. My mic picks up a lot of noise and I tend to breathe heavy so my audio needs extra editing to reduce it. My #maono mic is good enough for what I need it for so I don't plan on spending any more money on equipment.

Update: Thanks to @furicle for this suggestion. I think it's about perfect:

Dear sound/audio folks and engineers,

[Update: just for clarity: I'm looking for a command line utility that will help me decide which of 70 audio recordings need amplification/compression/normalization. Something that can print out media stats like average loudness, or something like that]

I have a directory with 3.5GiB of audio files (chiefly opus & m4a) which are spoken word recordings.

Some of them are quite low, and some of them are quite dynamic such that it's a whisper at times and nearly a shout at other times.

I've processed a lot of them with #audacity's compressor filter or #ffmpeg (ffmpeg -i audio.m4a -filter:a "speechnorm=e=50:r=0.0001:l=1" audio-normalized.m4a), but there are some unprocessed files in the collection, which are a pain to individually find and fix.

Is there a way from the #CommandLine to detect the loudness and/or dynamic range of audio files so that I can automatically flag them for processing with ffmpeg?

Thanks!!

Continued thread

oh BOY. So this morning my cousin replied to my edit request asking him to take my mom’s addresses down. This was his reply:

“Anne's residential history is important for me to document. I did take your other suggestions. By the way, if this is Maggie, I say Hello! I'd love to know how to reach you, where you are living and how to reach your brother. Thanks, Robert”

I LOST IT. Bruh NO. I discovered that this website is actually part of #ancestry, and according to their terms of use publishing people‘s addresses is a violation.

It’s impossible to contact this company but I did find six different email addresses for them so I emailed all of them and I copied the Attorney General in New Hampshire and the Attorney General in Utah where the website is based. I don’t know the rules about websites but I’m pretty sure they’re supposed to be some kind of mod or ability to stop just anything from appearing online, there’s no report button anywhere except to report a duplicate grave (ooh maybe I should make one then report his as a duplicate?) but WHY WOULD I GIVE HIM MY INFO AFTER THIS.

Oh, and EVEN WORSE. The entry he made for my grandma has all of her addresses on it, but the entry he made from my brother and my father and his father do not. He’s literally only victimizing women. There is no legitimate reason it’s important for him to publish all my mother’s addresses. If for some bizarre reason he needs this information for himself he can keep it in a drawer at home.

Anyway I don’t know how to reply to him so I suggested another edit thru the site and I pasted the body of the email I sent to the AGs in it. AND the paragraph from terms and conditions that says he can’t do this.

PLEASE if you have your burial plot, maybe go make a blank entry on this site so no one else can make one and write whatever they want to about you because apparently that’s a thing and there’s no way to get it taken down swiftly. I never imagined anyone with seize control of entering my family on find a grave website and then refuse to respect my wishes regarding private information. He even made an entry from my father‘s parents, for a grandmother who was dead before my father even met my mom. The absolute #audacity.

Ich denke ein Zehnjähriger kann mit #Audacity und einer Maus grundsätzlich klar kommen, wenn man ihm zeigt wo er sich verlaufen kann und wie er den Weg zurüxk findet wenn er sich verlaufen hat (rein-rauszoomen, undo, wechsel zwischen den verschiedenen Bearbeitungs-Werkzeugen)

Just did an edit of an episode of @retroadventurers.bsky.social yesterday, and I have to say there's a very rough sort of experiential bias this causes. I spent so long zooming in on regions where participants momentarily tripped over their own tongues, lost their trains of thought, or otherwise flubbed up. I played these bits over and over to find just the right section to mute or cut out. It left me with a false memory that everyone had just made a hash of it.

I just played the full episode in the background while doing other things, and I was left thinking "Gosh, this is a great episode!" I'd love to take credit for a stellar edit or whatever, but really it was just obvious: these were all the bits I wasn't focusing on the previous day, run end-to-end! #InteractiveFiction #podcast #Audacity #editing
