What is Reddit's opinion of Sonic Visualiser?

From 3.5 billion Reddit comments

Yeah, it's possible. It'd be a pain to do so, though. Aphex Twin hid a picture of his face in one song, you can see pictures of it online or if you have a spectrogram program like Sonic Visualiser.

So, I'm not an engineer- but I did do sonar for 6 years and understand gear mesh noise very well.

The best way I think I can help is if you give me a lofar readout using software like this

http://www.sonicvisualiser.org

It's free- I have more expensive software on my computer. Most of your gear noise is due to imperfections and reducing it will mean tighter tolerances in manufacturing which does not sound feasible given your situation.

I think your solution will likely be to encase the gears, find out if your case is resonating from the internal noise, and then soundproof/ or cut out the resonance.

If you pm me, I'd love to see if I can help out- I've been itching to do some acoustics work.

I'm assuming the team thought of everything, even knowing that it may not be true.

> Regardless, that is some seriously impressive technical investigation. Where did you learn this stuff?

I don't think I can point to a single place and say "I learned it all from there". I just got curious and tried to look for clues everywhere. I can tell you the tools I used, though.

• <strong>FFmpeg</strong> for decomposing the scene frame by frame.
• <strong>Sonic Visualiser</strong> for taking the spectrogram.
• <strong>grep</strong> for selecting the candidates from the wordlist.

I haven't worked out how to demodulate the handshake with hardware yet, but it's pretty cool in a spectrometer.

You can actually see the phases in the handshake and compare them to this table.

It hurts my old when the youngins think this is an alien sound. First modem I played with was 300 baud for a Commodore

I've heard people used to play records on a slower speed and tuning the guitar down in order to "break down" the song to play it by ear. These days, sound engineering software can slow down a song without changing the pitch, but with some electronic distortion. It's a SPECTACULAR method for learning solos...also, you can just loop the specific part of the song you're trying to learn.

Here's a free, basic example of the software I'm talking about: http://www.sonicvisualiser.org/

Sonic Visualiser is an application for viewing and analysing the contents of music audio files.

This program has numerous plug ins. I use as a support for finding the more exotic chords and harmony's used in (other people's) songs. But it can do much more.

I played the notes in sequence (about three seconds each), recorded with a basic Tascam recorder and built-in mics, then used the spectrum analysis feature of Sound Forge. Many other programs will do something similar: Sonic Visualiser is a good one.

Tonal balance, stereo width, dynamic range/punchiness, overall loudness. Those are the main ones. As far as tools, since I've bought into Melda I use MLoudnessAnalyzer for R128 LUFS, MAutoDynamicEqualizer to generate (and sometime match) the tonal profile, and I use Audacity to find clipping and Sonic Visualizer for more detailed analysis.

Ears come first, but the mathematical/visual tools help get into the ballpark really quickly, then ears for final adjustments.

One thing I've been playing with lately is phase sculpting for mastering, TL;DR of that is play with LP10 (CM version works too) or DMG Audio Equilibrium phase modes.

(This is an official /r/audioengineering type question and reply, fwiw)

Sonic Visualizer! 100% freeware, does what you ask perfectly

Also Reaper, import the song, move the "Rate" slider but right click it first and make sure it doens't change the pitch.

You should check out Sonic Visualizer and Chordino which can give you chords for a song. Just do File-Import and then Transform->Analysis by Plugin Name->Chordino->Chord Estiimate.

I happen to have this song and ran it through it: the intro is F# C# E Emaj7 and then the chorus is f# C# E B. The verses are hard to read but looks something like F#aug C#m F# C#m F# Ab7 Eaug A6.

Collect some youtube playlists of the stuff that you're interested in and play along.

You can also download the playlists with youtube-dl and import them to a media player like VLC that lets you slow them down or loop sections between cue points.

There are other tools like Sonic Visualizer that can extract charts from digital audio that can be useful for ear training, if your having difficulty with chord voiceings.

http://www.sonicvisualiser.org/ This program is crazy awesome. It can basically build you a piano roll as long as the timber of the instruments are not to distorted or crazy. You can even hear a midi version of what it thinks the notes are.

The downside is that it is fairly complicated and it takes some time to learn how to use it. If you are a computer-type person playing with music it'll be great. If you're a music-type person playing with computers . . . it might just be easier to learn the song than to learn this program.

I really like Sonic Visualiser. Hard to describe all of the different things you can do with it. Give it a peak. It's fascinating stuff.

Grab the VAMP plugins too, while you're there.

Excel is not the best choice. Software like http://www.sonicvisualiser.org/ is better suited for analysys. Recording has to be done separately, though. It has enough choices to visualize large amount of audio data (with enough processing time).

I've thought of that recently, I tried, but I didn't have many raw files of songs. But I think it is very possible for something like that be in a sound like that old recording machine that produces weird sounds in ZNS. Someone that has more knowledge in audio should try it

Edit: I found ZnS song and Samantha's lullaby in flac, but nothing came up.

For anyone wondering, I used this program: http://www.sonicvisualiser.org/download.html And selected:Toolbar/Layer/Add Spectogram/All Channels Mixed

Sonic Visualizer. It's normally used for music/audio research, so it has a bunch of functionality you might find interesting, plus, it just happens to have "save as image", which exports your visualization as a PNG (even lets you select a region). It's also free, as in GNU License.

Great answer, thanks a lot!

I'll try to find those papers and read more about the algorithms involved.

And yes, it looks like librosa is doing a pretty awesome job here. I'll check it out when I have some spare time. The librosa tutorial also points to Sonic Visualiser which is an amazing tool. If you've never tried it before, check it out!

The most powerful (and free/open source) is http://www.sonicvisualiser.org/, but it doesn't work with your DAW, it's standalone.

That said, it has a whole set of plugins that do some amazing things, such as automatic key detection, note detection, etc.

You can learn a TON by bouncing out a few of your tracks when doing sound design with this, OR drop in whole songs and see how they work.

I used audacity, but it is not versatile enough for me to make a lot of notes. Sonic visualiser (http://www.sonicvisualiser.org/) is free, though a bit more complicated. You can add a note anywhere on the waveform or ~~fft~~ spectrogram.

Sonic Visualizer is free and easy to use. I believe it is a stand alone program though... Izotope's RX2 is a great plug-in that will help you visualize the audio, as well as contains many tools for cleaning up the audio (de-clipper, de-noiser, etc). That will cost some $, unless you pirate it.

Maybe you could use sonic visualizer for analyzing the frequency (pitch) shift. The program is designed for analyzing audio, and has some decent pitch analyzing plugins. These have to be downloaded seperately and can be found on the same site (under Vamp plugins.
