I saw in Animating subplots using Plots.jl efficiently that there were solutions to make the animation go faster, using the same methods as function 3 and 4 of the answer

I am using gganimate to create animations of multiple frames of scatter plot with each frame corresponding to one year. I want to emphasize the change between two particular consecutive frames so that these two frames stand out frame other frames. But I am not sure how to do this.

Here is a sample of my data and code:

I am trying to detect sudden loud noises in audio recordings. One way I have found to do this is by creating a spectrogram of the audio and adding the values of each column. By graphing the sum of the values in each column, one can see a spike every time there is a sudden loud noise. The problem is that, in my use case, I need to play a beep tone (with a frequency of 2350 Hz), while the audio is being recorded. The spectrogram of the beep looks like this:

As you can see, at the beginning and the end of this beep (which is a simple tone with a frequency of 2350 Hz), there are other frequencies present, which I have been unsuccessful in removing. These unwanted frequencies cause a spike when summing up the columns of the spectrogram, at the beginning and at the end of the beep. I want to avoid this because I don't want my beep to be detected as a sudden loud noise. See the spectrogram below for reference:

Here is what the graph of the sum of each column in the spectrogram:

Obviously, I want to avoid having false positives in my algorithm. So I need some way of getting rid of the spikes caused by the beginning and end of the beep. One idea that I have had so far is to add random noise with a low decibel value above and/or below the 2350 Hz line in the beep spectrogram above. This would ideally, create a tone that sounds very similar to the original, but instead of creating a spike when I add up all the values in the column, it would create more of a plateau. Is this idea a feasible solution to my problem? If so, how would I go about creating a beep sound that has random noise like I described above using python? Is there another, easier solution to my problem that I am overlooking?

Currently, I am using the following code to generate my beep sound:

I generated a .dat file with 100 matrix 15x15, now I want to create a gif which shows the evolution from the first to the last matrix. They are all matrix with 1 or -1, so if I want to represent the inicial matrix I can copy and paste it in another file and I put this in gnuplot:

I am trying to ftruncate a shared memory object to a specific length. For example, I want to set its length to 1 byte using the following snippet:

In this bar chart race, with a Y-m-d date format ("2010-11-30… etc"), the gif (below) runs through the dates fine...

...but when I convert those same dates to a %Y %b format ("2010 Nov… etc"), months are missing throughout the animation, as shown in this second gif, below

Furthermore, I’d ideally like the date to be displayed as %b %Y format (Nov 2010… etc). I've spent weeks trying to sort this out but to no avail. Any help would be appreciated.

Here's the code

[Edit: In summary, this question was the result of me making (clearly incorrect) assumptions about what endian means (I assumed it was 00000001 vs 10000000, i.e. reversing the bits, rather than the bytes). Many thanks @tripleee for clearing up my confusion.]

As far as I can tell, the byte order of frames returned by the Python 3 wave module [1] (which I'll now refer to as pywave) isn't documented. I've had a look at the source code [2] [3], but haven't quite figured it out.

Firstly, it looks like pywave only supports 'RIFF' wave files [2]. 'RIFF' files use little endian; unsigned for 8 bit or lower bitrate, otherwise signed (two's complement).

However, it looks like pywave converts the bytes it reads from the file to sys.byteorder [2]:

I'm trying to decode some audio which is basically two frequencies (200hz for a 0 and 800hz for 1) that directly translates directly to binary. A sample of the audio

This sample translates to "1001011". There is a third frequency that is 1600hz as a dividor between the bits.

I can't find anything that works i did find a few things but it either was outdated or just straight up not working i'm really despaired.

I made a sample code that can generate audio for this encoding (to test the decoder):

I'm trying to animate a map graph using gganimate but am running into the following error:
