pitch

问题 Let’s say you have an audio variable called audio and it stores a sound. I know how to change the speed for example: audio.playBackRate = 2; But I don't know how to change the pitch. Is there an audio.pitch attribute or do I have to create it myself? I want to do something like this: var audio = new Audio(); audio.src = "sound_effect.wav"; audio.pitch = 2 //doubling the pitch but there is no pitch attribute audio.play(); 回答1: I think you need to use a library to apply pitch shifting to your

问题 I am using text-to-speech in my python project but not getting any way to increase or decrease the pitch level of the local machine voice in python. Here is my basic code: import pyttsx3 import datetime import speech_recognition as sr import random print("Intializing Toretto") engine = pyttsx3.init('sapi5') voices = engine.getProperty('voices') engine.setProperty('voice',voices[1].id) engine.setProperty('rate', 210) def speak(audio): engine.say(audio) engine.runAndWait() 回答1: you should add a

Closed 2 years ago . I need any python library to change pitch of my wav file without any raw audio data processing. I spent couple hours to find it, but only found some strange raw data processing code snippets and video, that shows real-time pitch shift, but without source code. 回答1: Since a wav file

问题 I'm looking to change the pitch and playback speed of some audio in real time with a slider, or a variable (i.e. while the sound is playing) in Xcode, Swift 4. Currently, I'm using AVAudioEngine, which allows me to set these values before playback starts, but I can't change them while I the audio is actually playing. Here is the code in question: func Play() { engine = AVAudioEngine() audioPlayer = AVAudioPlayerNode() audioPlayer.volume = 1.0 let path = Bundle.main.path(forResource: "filename

问题 The documentation for Audio Queue Services under OS 10.6 now includes a pitch parameter: kAudioQueueParam_Pitch The number of cents to pitch-shift the audio queue’s playback, in the range -2400through 2400 cents (where 1200 cents corresponds to one musical octave.) This parameter is usable only if the time/pitch processor is enabled. Other sections of the same document still say that volume is the only available parameter, and I can't find any reference to the time/pitch processor mentioned

问题 Recently I saw a video lecture in my CS 101 class that inspired me to start playing with the WAV File Format in C. My project today has been creating sounds using a simple mathematical sine function. Despite a couple obstacles, my program can now accept several inputs(frequencies of waves, amplitudes of waves, sampling rate, etc.) and create a wav file containing the specified pitches. However, when playing these tones on my computer speakers, there is a strange, rhythmic popping sound, which

问题 My group is developing a simple MATLAB Graphical User Interface (GUI) that is supposed to record audio from a microphone - plugged in or built in to the computer - and play back the signal. So far we have that completed. Our GUI also can load a sample (a .wav file, etc..) and play it back using the same "Play" pushbutton on the GUI. We have a Play, Record, Load, and Save push button. Now for the pitch-shifting of loaded or recorded samples... We know we need a peak-picking algorithm to find
