aubio

问题 I want to record sound of a machine and want to detect if its present in another sound file that I record. I am able to record the sound of the machine and the sound file that I want to detect its presence. I am also able to take fft of the sound files, however I dont know If I should check specific frequencies or check it in time intervals. Can I implement it with aubio or is there another way? silent room silent room + sound 来源： https://stackoverflow.com/questions/53305661/detecting

问题 I'm trying to use the aubio(https://aubio.org) library for pitch detection. I'm trying to use the API for C and one of the parameters of the new_aubio_pitch function is hop_size . What does hop_size mean and how do you choose one? 回答1: Hop Size should refer to the number of samples in between successive frames. For signal analysis, Hop Size should be less than the frame size, so that frames overlap. In this diagram the Hop Size would be 'Q' and 'K' is the frame size for a signal 's(n)' If

问题 I want to use the aubio module to extract pitch using python 3.5. However, the documentation is difficult to comprehend. In example I have a numpy array: import numpy import math sample_rate=44100 x=numpy.zeros(44100) for i in range(44100): x[i]=math.sin(i/225) How to use aubio to extract an array containing the pitch of the array? 回答1: Here is an example (works python2.x and python3). Note the changed sinewave generation. #! /usr/bin/env python import numpy as np import aubio sample_rate

问题 I'd like to use aubiopitch to continuously output the frequency of a signal coming from an input source. Since aubiopitch likes to have its input be a file, not a stream, I tried using process substitution: $ aubiopitch -i <(sox -q -d -t wav -) I'd expect this to output the frequency of the signal being read off of my default audio input device. Instead, I got this: ./sox WARN wav: Length in output .wav header will be wrong since can't seek to fix it AUBIO ERROR: source_apple_audio: Failed

问题 Aubio is a tool, written in C, that analyzes sound files. It is compatible for android, ios and many more platforms. My Question: Is there a step by step guide on how to build aubio for android - or at least a list of all the tools needed (waf, ndk, CMake, etc.) and how and when to use them? I have only developed apps for android in java before. I just want to run a simple given example from the project. I have already read the developer guides for android ndk and tried to figure out what to

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 4 years ago . Anyone know of: A build of the Aubio library for iPhone/ARM processor? An intro-to-cross-compiling resource so I can try it myself? 回答1: Try using the latest git: $ git clone git://git.aubio.org/git/aubio $ cd aubio/ $ ./waf configure build --with-target-platform ios 回答2: I've
