To just restart the song, you’d do: function play() { var audio = document.getElementById(‘audio1′); if (audio.paused) { audio.play(); }else{ audio.currentTime = 0 } } FIDDLE To toggle it, as in the audio stops when clicking again, and when click another time it restarts from the beginning, you’d do something more like : function play() { … Read more
The simplest solution is to just reset the audio currentTime and ensure it’s playing using the play() method. Checking if the audio is playing is not necessary as subsequent play() invocations will not do anything. audio.currentTime = 0; audio.play();
Use scipy.signal.spectrogram. import matplotlib.pyplot as plt from scipy import signal from scipy.io import wavfile sample_rate, samples = wavfile.read(‘path-to-mono-audio-file.wav’) frequencies, times, spectrogram = signal.spectrogram(samples, sample_rate) plt.pcolormesh(times, frequencies, spectrogram) plt.imshow(spectrogram) plt.ylabel(‘Frequency [Hz]’) plt.xlabel(‘Time [sec]’) plt.show() Be sure that your wav file is mono (single channel) and not stereo (dual channel) before trying to do this. I highly … Read more
I’m the developer of Construct 2, so I hope I’m sufficiently qualified to answer your question 🙂 HTML5 audio is indeed a mess, so I’ve gone to considerable lengths to try and make it bulletproof in Construct 2. Here’s an outline of what I’ve done: Use the Web Audio API HTML5 audio appears designed for … Read more
Maybe you can convert the C/C++ code here to C#: http://www.firstpr.com.au/dsp/pink-noise/ The easiest way to get sound to the sound card is to generate a wav (spit out some hardcoded headers and then sample data). Then you can play the .wav file.
You’re looking for something more generic: HTMLMediaElement, here are some reference guides: https://developer.mozilla.org/en/DOM/HTMLMediaElement http://www.whatwg.org/specs/web-apps/current-work/multipage/video.html#audio https://developer.apple.com/documentation/webkitjs/htmlmediaelement
Given a File you can write File file = …; AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(file); AudioFormat format = audioInputStream.getFormat(); long frames = audioInputStream.getFrameLength(); double durationInSeconds = (frames+0.0) / format.getFrameRate();
The reason why event bubbling exists is solve the ambiguous question of which element is the intended target of the event. So, if you click on a div, did you mean to click the div, or its parent? If the child doesn’t have a click handler attached, then it checks the parent, and so on. … Read more
