But I suppose that most of the despicable distro lackeys
on this NG couldn't tell an audio file from a hole in the
ground -- let alone edit one.
Cite your fave audio file editor.
Note: I refer to programs that edit AUDIO FILES and
not gigantic and comprehensive music editors.

Adobe bought Syntrillium Software in 2003 for $16.5 million and Cool
Edit Pro became Adobe Audition. That's how good it was.
And it still is.
Cite your fave GNU/Linux audio file editor.

Got that?
My faves are as follows:
Snd

Mhwaveedit:

Sox:

Cool Edit Pro 2.1 on Windows.
Digitize vinyl records that will never
be available on CDs.
I initially save all of this stuff as .wav files (CD quality).
I use it to record the audio of favorite movies
(streaming from whatever or from DVDs), to listen to on long road trips.
I mostly use
ffmpeg both for video and audio encoding decoding and editing
and to extract audio from video, edit it, chance encoding format etc.
all command line
And sox of course.
mplayer for audio / video playback

It is best to see the actual waveform, and for that mhwaveedit and snd
are very lightweight and fantastic.
The list of GNU/Linux sound utilities is quite long.
For example, after recording there is often a need to "normalize" the >waveform. For that, the "normalize" utility my go-to program, but sox
is also able to normalize.
<https://normalize.nongnu.org/>
Of course, it is critical to check for audio clipping. For that there
is sox:
sox file.wav -n stat
Then there is sndfile-info from libsnd:
<https://libsndfile.github.io/libsndfile/>
mplayer for audio / video playback
Is that still around? MPV is better:
<https://mpv.io/>

Oh well. Such is expected.

Does it remove those annoying pops and clicks?
Answer: Fuck no. For that one must turn to GNU/Linux:

QED. Only an idiot saves in WAV format. The informed user always

Thank you for the links, have already forwarded those links to somebody in sci electronics.design
who is into cleaning up old records.

Yes, but I also have a real osciloscope.
I usually write whatever I need or are interested in...
Design and build hardware too, download site:
I often type:
mediainfo filename
to check what I am dealing with.

I also (or used to) design and build mostly audio circuits.
Perhaps a new thread on GNU/Linux EE should be started.
These helped me a great deal:

The Gramofile link contains the source code which is "old."
It may need to be patched. Some distros have the patches
and updates but others may not.
Debian seems to have the source and the full patch set:
<https://packages.debian.org/sid/gramofile>
I no longer digitize vinyl but if I did I would apply
these Debian patches.

I didnrCOt know about that one. I often use ffprobe (part of the FFmpeg >suite) to get details on the format, streams, codecs etc in a media file.
It can even drill right down to tell you where each packet of each stream >is, and what its PTS value is. This is handy for decoding custom stream >formats (e.g. instrumentation, GPS, inertial navigation).
How does an oscilloscope enable viewing of an audio file?
My PC and even my older model Raspberry Pi has an 3,5 mm audio jack output Connect scope to it, play audio file with whatever player you have and see the wave forms.

This is converting a digital file to an analog output and
then viewing the analog voltage on an oscilloscope.
A digital audio editor, like mhwaveedit, allows viewing
of the actual digital samples. There is need for the
conversion step.
I discovered in the Raspberry Pi case there was a lot of RF on the audio output.

It could, I think they use some sort of pulse width modulation to
make the audio, the high frequency pulse might cause interference,
but in an audio amplifier, if it is one with a good high frequency
response, it will be amplified and enter the speaker wires and then
for sure cause interference. The other thing about that that I do not
like: if you use earpieces on the 3.5 mm jack then your ears will be
exposed if the thing can vibrate at that frequency, and by that RF. I
even avoid wireless earpieces and cellphones next to my ear if I can.
Those wireless earpieces also transmit. In your ears for hours?
I am radioham too, and have had high power transmitters close to me.
But square of the distance law counts, IN you ear is not good.
I have experimented with PWM audio:
https://panteltje.nl/panteltje/pic/audio_pic/
I had some PWM audio power amps from ebay but those did not last...
Still using good analog audio amplifiers here. This one I build 20
years or so ago, is on large parts of the day, not only for audio but
for all sorts of experiments for example making 60 Hz to power US
stuff that needs 60 Hz main via a step up transformer (am in Europe
50 Hz mains here)
https://panteltje.nl/panteltje/amplifier/index.html
My main audio amplifier is this a McCrypt PA3000:
https://manualmachine.com/mccrypt/pa3000/18654443-operating-instructions/
has been working great for many years now :-)

Hi Jan,
Wanted to point out that your newsreader doesn't seem to give
attributions for the people you're replying to.
Is that intentional?
