Is there any arduino libraries for shfiting the pitch of audio? I'd like to make something like http://hackaday.com/2011/03/17/pitch-shifter-makes-your-band-sing-higher/ but I'm not sure if I can with arduino. I don't need all the code, just a guide as to what library to use. Thanks!

The last Friday of the month is a build day around Instructables HQ. I've been meaning to create some art involving gears of different pitches, so I took part of my build day to do a study in gears. These are two laser-cut acrylic gears I made on our Epilog 36EXT that are half 10 in pitch diameter and half 20 in pitch diameter. I advanced the 20 pitch side about one-half of a pitch. The gears were designed in OMAX Layout, which just happens to have a nice gear profile generator. I'm hopeful about putting together a set that gradually change pitch diameter.There's a bit of slop between the gears, and I'm taking advantage of it (at least in this set) to keep the teeth from colliding at the transition. They only rotate freely in one direction; in the other they bind.

Here's one for you... I'm looking to create a 70 note bottle organ, inspired by this video: http://www.youtube.com/watch?v=WzucpFgi7Xk Except I'm wanting to build mine in a more "automatic" state - played via MIDI notes, an arduino and lots and lots of solenoids making spoons hit the bottles.. That side of it I've got covered thanks to other excellent instructables which have taught me a lot about micro electronics. What I am currently trying to work out is if there is a way to change the pitch of bottles in any way except simply adding water. Would another liquid achieve the same results with less "spill risk"? Does it even need to be a liquid? I'm guessing it needs to be a liquid as I believe the physics of the noise made when a bottle is struck is based on the water absorbing vibrations, making them slower and lowering the pitch. If anyone has experience tuning multiple bottles to be struck as an instrument then please do reply! Alternatively if anyone has any novel suggestions for things which would be easier to persuade 70 notes out of then please also reply! End goal - be able to play flight of the bumblebee at full speed with chords and out-nerd the guys in the video. Ideally on bottles. Many thanks! Leo

I'm looking for sockets like the ones pictured but I'm not having any luck. I guess I don't know what to search for. What I'd like is a way to make cables to connect PCBs together. I'd like to buy the sockets and wire them up myself. I'd also like 2 pin and even 1 pin versions. At a job I had a while ago they had wires with single sockets on the end that were very handy for connecting to standard .1" male pin headers. If anyone has any idea where to find these sockets or what to search for on Digikey I'd appreciate it.

Well I recently inherited a old TV it is an SDTV and it is about seven years old. So I decided to test it with my computers osciloscope and using the microphone on it i turned the osciloscope on and there was one constant signal that went up and down about 3 or four KHZ every second or two. But when I muted the TV their was the normal background noise at about 1-7 KHZ but one signal that I found is about 16-17 KHZ and 5.94 DB, and when I turn the TV off it stops and that 16-17 signal disapers. So how do I get rid of this annoying high pitch noise?

I'm making a keytar and was planning on finding a keyboard with the number of keys that I want and a MIDI output, but I'm thinking that if I do find a keyboard, it won't have the pitch-bend functionality. Could I have an Arduino read a membrane potentiometer and send that out the same MIDI port that the keyboard is sending the note data out of and have the pitch bend affect the note?

I am building an electronic version of an old Brazillian instrument called a Berimbau. Part of it is played by moving the cabaca or gourd closer to or further from your body. This movement bends the pitch or mutes the output. I'm attempting to replicate this effect with a proximity sensor that will do the same job as I move the instrument back and forth from my body. My problem is all the sensors i find are just on off switches. I need something that will increase gradually with the distance. So if anyone out there has a solution then do please help! On a note tho there is a device available for guitar called a wah probe. It is exactly what im attempting to build but costs in excess of £300 so when the first thing i will be doing is dismantling it and hacking up the copper plate i dont see the point in wasting the money! Especially when it will probably take several attempts to get right...

I know how to tune everything but the D string. I keep going up and down with the fine tuning, but to no avail. Here's what I've got: -Violin is made in China, but it's somehow better and lasted longer than most violins here in the PH (Philippines) -I have a pitch pipe to assist in tuning, but when I hit D, it's somehow muffled (in a way) and I can't hear it clearly, so I can't differentiate between what I'm playing on D at the moment, and the pitch pipe output.

I made a very simple pitching machine...actually a soft toss machine. It is a pvc pipe assembly that when set up, dad simply "loads" a ball in the downward angled pipe and it "drops" in front of the batter. My question is: the downward angled pipe can be long enough to hold a dozen balls - what can I use to create a mechanism that allows one ball to drop every 5 seconds automatically?

Ever since I built my gaming computer, my HP monitor which has speakers in it makes a ringing sound. What is weird about it is that when my CPU is occupied for a second or two (Like opening Google Chrome), it stops and when it is done processing that it starts back up. It also stops when I lay my mouse over certain things or put a drop down list. It's a very high pitch sound that everyone I ask says they don't hear anything. However, I can hear it like one of those old chunky TVs that make a high pitch sound on start up. It's very distinct to me and it's annoying. I know it is my speakers making the sound because whenever I unplug them they stop making the sound. Any possibility? Motherboard malfunction? My speakers on plugged into the green port on the back of my computer. Thanks!

Need: Ceramic mug (shape doesn't matter), hot semi-skimmed or full-fat milk, metal teaspoon. When I give the milk a good stir, then begin to tap the bottom of the mug (inside) with the spoon, the pitch of tapping rises gradually. When I stir the milk thoroughly & then start tapping again, the pitch resumes its ascent from the original lowest note. If I only give a partial stir, the pitch resumes partway up from the lowest note. What's going on?
I'm not real familiar to the in depth functioning of the Theremin, but I think I have the general gist of how it works. Specifically, I was wondering If it was possible to use a Theremin to change the pitch of a sonic screwdriver. One of my qualms with sonic screwdriver replicas is that they lack the changing pitch of the screwdriver in the show (Doctor Who, to the uninitiated). After reading about Theremins, I wondered if one could be built into the case of a sonic screwdriver (DIY with metal case) allowing the pitch of the sound to be altered in relation to its proximity to the users hand(s) and the environment. Has anyone ever heard of something like this being done?

I'd like to make a low frequency triangle wave oscillator/sequencer, but the oscillator and sequencer have to somehow be synchronized with each other, so that if the tempo gets doubled, for example, the pitch also goes up one octave. How can I do this? I've already made a circuit based on this oscillator and the 4017 decade counter as a sequencer. (Ignore all capacitor, resistor and pot values; I haven't defined them yet)

I'm a real Noob to this electronics thing (but I find it fascinating..). Anyway, I want to try to build a device that beeps. The duration of the beep is fixed, but the frequency and pitch should be variable, depending on user input. The whole device should be as small as possible and water proof. I would prefer to be able to control the beep frequency and pitch remotely - perhaps from a mobile phone or from something like a remote controller. The beeping unit should be kept simple as possible. Any ideas on how I can achieve this? Thanks, Yossi

Question by Clayton H. | last reply
Hi Folks, I'm searching for some info on how to make a visual "Click track" aid. In one of my bands, we use a click track on some tracks and live on others. I use a single in ear monitor for the click track which s fine for most tracks, but for some, I need the click fairly loud and this cannot be good for the old lugs long-term. So, I want to make a small LED display or two that can react to an audio signal that is fed from the click track channel. I've seen many instructables that show how to make LED blink/flash etc to music, but my requirements are a little different (I think). The click at the beginning of each bar is higher in pitch and has a higher velocity compared to the other click in that bar, so for example; Playing in 4/4 time signature: click 1 - Velocity =100 - pitch C5 click 2 - Velocity =90 - pitch C4 click 3 - Velocity =90 - pitch C4 click 4 - Velocity =90 - pitch C4 If playing in another time signatures ie; 3/4 or 6/8, then I would also need to cater for this in the display Questions: 1. Does anyone know how I could devise a system that would light a Red led for beat 1 and then perhaps a white (or other colour) led for the rest of the beats, but in a sequential fashion? 1,2,3,4. 2. Is it possible to change which led flashes based on either pitch or velocity? I could even make the front of the led display show actual numbers over a perspex cover so at anytime, a quick glance will show me exactly where I am in the bar. So rather than coloured leds. So to recap, I'd like to be able to take an additional audio feed from the click track channel from a mixer, into this new "drummers visual click track aid" device and have it react to the clicktrack and display that in the form of beats per bar based on either pitch or velocity of the click track. I currently use a couple of wood block sounds for the click track because they are very clean and short. Many thanks for taking the time to read through my requests and if you're the kind of clever person who could make such a device, I'd be more than happy to pay you for your input and suggestions. Many thanks in advance and I look forward to hearing from you soon. Cheers Phill
