Most likely by telling Java the input mixer you want to use. Check out the section “Setting the System Mixers” on this page: http://code.compartmental.net/tools/minim/manual-minim/

How can I get the an external USB mic as the audio input?

The Minim library works fine with PulseAudio on Linux!
Using Pulse Audio you can route minim’s audio input to whatever sound source is available(mic,line in,monitor of the soundcard output,etc).

Unfortunatelly the official Oracle java 1.6 does not support pulseaudio for JavaSound.But there is an SPI and a native library included in the IcedTea project.

It would be ideal if Minim could use Jack Audio for sound input-output,which is designed for pro-audio realtime applications.

What this class does is give you access to the audio data from the active input on the computer. If you want to analyze the samples to get the frequency spectrum, you’d use an FFT object and pass in the mix buffer of your input. It’d be the same code as shown on the the FFT manual page (http://code.compartmental.net/tools/minim/manual-fft/), only you use an AudioInput instead of an AudioPlayer.

The easiest way to pipe the input to the output is now the LiveInput UGen (http://code.compartmental.net/minim-beta/javadoc/ddf/minim/ugens/LiveInput.html), which you can use by downloading the Beta release on the main Minim page. Start at the Music Programming Intro section of the manual to learn about that new framework.

does anybody know how to analyze frequencies from audio input? seems like this class, along with waveformrenderer, only analyzes individual samples.

“To do that, you’d need to pipe the input back through an AudioOutput object.”

trying to figure out how to do this. audiooutput takes in audiosignal objects, and i’m not sure how to convert audioinput to audiosignal, if that makes any sense. anybody have any pointers?

i found this library because i was looking for a alternative to sonia+soniaHelper, so im quite curious what your progress was on the implementation.

thnx

1) I’ve not used SoniaHelper so I don’t know exactly what the damper you are talking about would be for. In the beta release that just went out you will find a Damp UGen in the UGen framework, which might be what you are looking for.

2) If you were to use the SoniaHelper damper in an AudioEffect, you’d write a AudioEffect for yourself that wraps the SoniaHelper damper. The float array you are looking for would be passed to the process method of your effect.

Hope that helps!

I recently switched from Sonia to Minim and I’d like to laud the work done on the library. Previously when I would use Sonia I would use it in conjunction with Marius Watz SoniaHelper to add a damper. I have a couple of questions concerning this:

1. Does Minim have an equivalent?

2. I didn’t find one so I started tinkering with the two together. SoniaHelper requires a float[] for it’s audio input values. I checked the some of the Javadocs (namely for FFT) and didn’t see any methods that returned a float[]. Could you point me in the right direction?

I think if the answer to the first question is no, I might try my hands to port SoniaHelper to a MinimHelper. Cheers
