kandi X-RAY | convolver Summary

convolver is a Python library. convolver has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. However convolver build file is not available. You can download it from GitHub.

My hope is that these tools are easy enough to install and operate, so that they can be used by people who don't necessarily have a Python background, to process images to improve them or just for fun.

Audio Convolution output is longer than input, how can i get around this when feeding data back to a stream of fixed length?

QUESTION

Audio Convolution output is longer than input, how can i get around this when feeding data back to a stream of fixed length?

Asked 2020-Oct-15 at 12:18

After taking audio data from a stream of length x, the data is then convolved with an impulse response of length 256. This gives the output vector a length of (x + 256 - 1). When the data is then fed back into a stream of length x there are 255 samples of overshoot that then causes popping and clicking.

Is there a work around for this? Im not 100% on how to merge the larger than original buffer into the output again without losing random samples or causing this issue.

I left out the larger irrelevent parts of the code, it all works its just this issue i need fixed. Its just here to give an insight into the problem.

You remember the 255 extra samples and add their values to the 255 samples at the beginning of the next output block.

Adding reverb to audio makes it distorted and loud

Asked 2020-Jun-08 at 15:44

i made a website for a game to produce record and share music, some users asked if i could add a reverb option to toggle on/off the reverb (this to simulate being inside a cave), i googled up a bit and found about the webAudio api reverb with the convolver node. I honestly didn't understand much about it but i tried to make it work, in the end i made this:

A convolver can certainly be used for reverb, but the "buffer" you want to give should not be the same as the audio you're playing. It should instead be given a reverberation kernel (or impulse response), which may be precomputed or an actual recording. It corresponds to how a space reacts to an impulse of sound. You can probably find a suitable royalty free kernel online, never looked for one myself though.

More about convolution reverb on Wikipedia.

QUESTION

Web Audio API demo doesn't work on iOS

Asked 2018-Jun-30 at 19:28

I'm currently working on adapting this web audio API demo for a project that I am working on, but there is no sound when I test on an iPhone. It works fine on the iPad.

I've searched for solutions and found this thread on StackOverflow with the following snippet of one of the answers:

Safari on iOS 6 effectively starts with the Web Audio API muted. It will not unmute until you attempt to play a sound in a user input event (create a buffer source, connect it to destination, and call noteOn()). After this, it unmutes and audio plays unrestricted and as it ought to. This is an undocumented aspect of how the Web Audio API works on iOS 6 (Apple's doc is here, hopefully they update it with a mention of this soon!)

The user input event should be the onclick event on the play button but changing to use noteOn() instead of start() still doesn't fix it.

Update: I've also tried binding the play button with the touchend event but to no avail.

Here is the function that uses noteOn():

The start() method should work fine without the if else statements on iOS as long as you call the function with a user interaction event. Also flip the order you pass y and z to the panner cause z is second for some strange reason. Here's a working example, change stuff in it to fit what you need, most isn't need and I've got others somewhere that use the dom to add event listeners
