Voice pitch detection software

To understand frequency, imagine if sound waves were visible. The higher the frequency of the wave, the less time would elapse between peaks of a wave passing a static point.

The lower the frequency of the wave, the more time would elapse between peaks passing a particular point. Imagine a high frequency sound as the ripples caused by dropping a large rock in the lake, and low frequency sounds as big, slow waves caused by a passing ship.

Your microphone detects your voice or instrument, and then converts that sound into an electrical signal. That signal is then interpreted by our tool and the frequency of that sound is deciphered and displayed along with the corresponding musical note. Also, the "random" behavior you're describing might be because you're grabbing data returned by your sound card directly without assembling the values from the byte-array properly. Did you ask your sound card to sample 16 bit values, and then gave it a byte-array to store the values in?

If so, remember that two consecutive bytes in the returned array make up one bit audio sample. It works fairly well on any computer running post real-time Java. The project has been dropped and could be picked up by any interested party.

My delightfully compact guitar tuner is able to detect the pitch of the strings pretty well. I see this reference to a piano tuner which explains an algorithm to some extent.

Did you ever solve the underling problem from those other questions?

The whole "random results" thing just sounds like you haven't got those methods working right, yet.

This problem seems to me to be very similar to detecting the pitch as done in the "Rock Band" game for vocals - and they seemed to get it to work quite alright. That makes me believe there must be a way to do it. It's just that by reading the Wikipedia article on pitch detection it seems that it's not quite a trivial problem. We hope you're going to post an answer here if you find a good method! For debugging, try whistling. The sound of whistling contains one very strong frequency with few overtones.

You should also visualise the output of the FFT, if you weren't doing so already. I have to agree with Thomas on visualization. Plotting a graph is a great way to learn about the properties of the sound you're analyzing.

Many people find the MS Windows operating system works best for general use programs, such as email, spreadsheets, internet browsing, and misc utilities.

However, for hard core graphics and audio work, most engineers agree that the Mac OS offers the superior platform. This tool enables you to correct and fix off pitch vocals after they are recorded. The Pitch-Tracking Modulation , unique to Graillon, changes the type of speakers, generates throat sounds, creates choruses, make octaver sounds, enriches a voice to make it more masculine.

The Pitch Shifter cleanly transpose a voice up and down, and has been optimized for voice. The Pitch Correction module brings an immediate robotic sound, while the Bitcrusher addition softly add sparkles to the mix. Skip to content. RoVee is a free pitch corrector VST plugin developed by gkg. Compatible OS s : Windows. This is what you get: You can change size and style of the plugins. You can access sonogram feature in analyzers and equalizers. You can manipulate your own presets.

Most plugins can perform upsampling which minimizes aliasing, therefore it is useful to improve sound quality. The plugins will not contain the nasty big box in the bottom with our clickable logo. You will make us happy and let us develop more free software;-.
