volume

问题 I wanted to write an alarm program, for waking up in mornings. I want it to play sound as loud as possible, so it needs to raise up volume to 100%. I also asked how to change volume with python?. @macmoonshine suggest me to use 'AppleScript'. it was good and worked for me, but it works only on python2(error on python3) and(not sure) only works for apple. how can I write a program that can control volume in python3 without using AppleScript? I'd appreciate your help(; 来源： https://stackoverflow

问题 Link of Previous Post: Matlab Questions about Audioplayer GUI I am trying to make a volume slider in Matlab... So currently what I have in mind from what I have searched is using handles variable to get the slider's value. After that, I am planning to have the variable multiply the (x,fs) in the audioplayer. My current code for the beginning of the handle is like this... handles.a = [] ; %I don't know what to put for this >.< handles.output = hObject; handles.myPlayer=[]; guidata(hObject,

问题 I am using Fedora 16 and modifying a program in python 2.7. How do I get the systems volume (Sound level)? 回答1: For ALSA, use pyalsaaudio For Pulse, its a bit raw. There are ctype bindings 回答2: If you are using ALSA, you can run 'amixer' to dump the state of all volume controls. For PulseAudio, I believe 'pacmd dump' should get similar info.

问题 I'm have written a C++ application that is running as a Windows service to limit the volume of a Windows 7 computer. The user can specify different rules for different days and times and the service will smoothly change the volume. To implement this I use the IAudioEndpointVolume interface. In general it works like intended... However, there exists a strange behavior I cannot explain yet. When switching users the volume suddenly drops but it does not generate a notification as one would

问题 I have a hollow cylinder with inner radius r1 and outer radius r2. This cylinder is tilted from the Z axis towards the X axis, then rotated around the Z axis and then translated along X and along Y. I also have a cube between a range of X and Y values. I then want to calculate how large a volume of the hollow cylinder is inside the cube. %set variables r1 = 0.9; r2 = 1.0; z1 =-1.0; z2 = 1.0; beta = pi/4; gamma = pi/8; %create inner surface [X,Y,Z] = cylinder(r1, 100); %outer surface [Xx,Yy,Zz
