            Changing values displayed in top right corner of matplotlib figure
            Asked 2022-Apr-16 at 14:37

            How can I change the values dislayed in the top right corner of matplot figure? By default it is showing coordinates of the current cursor position but I'd prefer it to show the value of displayed data for current x cursor's coordinate. I marked these values in the attached picure. diagram

            Here's a simple code. Pls tell me how to solve described problem for this example:



            Answered 2022-Apr-16 at 14:37

            You have to retrieve the x-value and use it as the index of your sound data list. As you have to check for the validity of the index, we define now a function NavigCoordin():

            You write the data in a file, the position within the file moves to the end of it. If you then re-read the file using soundfile, you must first jump back to the beginning of the file.



            Snakefile how to mix wildcards and variables
            Asked 2022-Feb-13 at 01:48

            I want to make a rule which for a given number of threads translates files in one directory and format to another directory and format, in parallel. Certain elements of the path are defined by variables and certain are wildcards. I want it to wildcard on phase and sample and ext but take stage, challenge and language from the Python variable environment. I want the copy operation to take file to file. I don't want it to get the entire list of files as input. I'm not using expand here because if I use expand then snakemake will pass the entire list of inputs as {input} and the entire list of outputs as {output} to the function, which is not what I want. Here is the Snakefile:

            Autocorrelation of a wave file
            Asked 2022-Feb-09 at 11:17

            I'm playing around with audio signal processing. For that purpose, I'm using a single channel wave file from here.

            My first experiment was to look at the auto-correlation of the signal as done by the following code.



            Answered 2022-Feb-09 at 11:17

            When you read your wav file data_a is an int16 array. The correlation will be calculated using int16 data type as well, this will cause a lot of overflow. To get a meaningful result you can convert it to a floating point array.



            swiftUI: strange behavior with AVAudioPlayer
            Asked 2022-Feb-02 at 21:38

            I want to build an Onboarding Screen for an app especially for blind people. so the pages should play a small mp3 file.

            But if I implement the code as attached, the behavior seems weird for me. If I change from page 1 to page 2 the first mp3 file stops and the second starts. as I want it. if I go further to page 3 the mp3 from page 2 continues and the mp3 from page 3 starts also. the both sound are overlaying each other.

            Answered 2022-Feb-02 at 21:38

            Any time you use !, you risk a crash if that value ends up nil. The easiest solution here is to make audioPlayer an optional.

            Second, in regards to your issue with overlapping audio, the tab probably isn't getting truly unloaded (and not called onDisappear). Instead of using onAppear and onDisappear, you could use onChange and watch the selection of the TabView (some of the AudioPlayer code is removed for brevity):



            Convert int8 opus-encoded array into raw waveform (Python)
            Asked 2022-Jan-20 at 07:30

            I have a js script that records audio from microphone and sends it via a websocket to a python REST API.

            how can I turn this array into a proper .opus or .ogg file?

            You're capturing a Webm file stream via audio/webm;codecs=opus, so that would need to be converted from Webm to Ogg Opus. Instead, you could simply download or send the Webm Opus stream as a file as-is:



            If a letter from group "x" play sound "a", if from group "y" play sound "b" + text formatting
            Asked 2022-Jan-08 at 22:20

            I've got that bit of code (see below) which randomly selects between letters A through to X. I created few characters empty space after each letter in string because I'm not sure how to do that otherwise, maybe some of you knows how to fix that as well? That would surely make the code look a bit more condense and neat.

            At the moment every time each of these letters gets selected one sound is being played (click_001.wav).

            I want to diversify it, so when it selects letters from A to P, it plays "click_001.wav", and when from Q to X, it plays "mouse_click.wav".

            I know the code won't work for you fully since you haven't got the wave file so in the link below I prepared the files ready to download if needed. I'm using "processing.sound" library in this example as well which can be added to processing via menu in processing: Sketch > Import library > Add Library > in the search bar type: sound. It's the sound library from The Processing Foundation.


            Could any of you help me with that, please?

            Best regards,

            You can drop the spaces in the 'words' array by just setting the x coordinate for each text call instead of using a variable. I added the letter 'K' which you apparently left out. Also added was a new function to play a sound for each character in the beat string. The two sound files need to be placed in a folder titled 'data' in the sketch folder.



            Python's SoundFile: soundfile.write and clipping
            Asked 2022-Jan-04 at 10:28

            Answered 2022-Jan-04 at 10:28

            The important question to answer here is not just what soundfile does, but how to confirm the behaviour.

            Let's keep this neat little sample program, which with some extra annotation is:



            Meaning of sample values in a wav file
            Asked 2021-Dec-23 at 15:09

            for a school project, I am supposed to analyze a short sound recording in wav format. I am done with the project, I DFT'd it, filtered out unwanted frequencies, and got the correct result. What eludes me, though, is the meaning of the values of the individual samples of my wav file. I have tens of thousands of samples that look like this:



            Answered 2021-Dec-23 at 15:01

            The samples (basically a long array of floating point numbers) in the file is the Pulse Code Modulated data representing the audio.

            Given that audio players use this data to recreate the original audio wave, multiplying every sample by some factor should increase the volume. However, some audio players scale down (re-normalize) the samples to prevent audio clamping - which can be the cause why it sounds the same.

            The ideal way to visualize the audio should be using Audacity. It has the capability to show the audio wave in real time. Something like this -

            Getting error while unit testing my machine learning model on Audio files
            Asked 2021-Nov-15 at 21:11

            I am getting errors when training my machine learning model which is for checking what a person is feeling while saying somthing. I am working with librosa, soundfile & MLPClassifier from sklearn. This is my code:



            Answered 2021-Nov-15 at 21:11

            Your call to os.path.basename("data/what.wav") returns 'what.wav'

            You then split that using "-" as the splitter, which returns ['what.wav'], a list of one element.

            But you then try to reference the third element of the list with [2], which throws an exception.
