![]() (numbers indicate the number of octave 1 ). These sounds are organized in sequence c1, c # 1, d1, d # 1, e1, f1, f # 1, g1, g # 1, a1, h1, c2, c # 2, d2, etc. According to the chromatic scale arranged are, for example, a piano keyboard (including black and white keys), or sounds of guitar string on the each following freet. Scale which is designating almost all the sounds used practically in music is the title chromatic scale. Such scheme "choosing" specific frequencies of their infinite spektum is called the scale. Almost all the music, we encounter and that we want to listen to is based on a jumps between the frequencies according to some scheme. Sounds created in this manner, however, are very specific in perception and far from music, to which we are accustomed and for which the human brain responds positively. This effect can also be obtained, by untuning randomly strings of a guitar, or pressing the strings of a violin or fretless bass at random points in the neck. In theory, we can play sounds freely selected frequencies and create music in this way (I encourage you to self-experimentation with the module "creating signals" available on this site). adopted by convention that the sound "a" in basic octave has a frequency of 440Hz). Recall that every sound has a frequency expressed in hertz (eg. To well understanding of the concept of chromatic, you must first become acquainted with the concept of the musical scale in a more general sense. that is chromatic scale (twelve-tone scale) and scales in general Process of searching right sound is repeated ten times per second, for currently processed sample sound from a microphone.That makes it possible to tune the instrument in real time. Such situations are indicated by the corresponding red LED on the screen. They are more similar to the sound of sound reference surroundings (higher or lower) than the specific sound scale. This allows catching out of tuned sounds. ![]() Additionally, program checks slightly higher frequency and lower than the standard frequencies (kind of surroundings of sound reference). Cosine wave is the sine wave shifted by & Pi / 2 (one-fourth of the period). In order to take account of the so-called phase shift, there is also performed a comparison with the cosine wave reference frequency. The higher the score, the greater the similarity. The result sum illustrates how wave entered through a microphone is similar to the pattern. ![]() Operation of the transformation is in this case multiplying successive points of the input waveform (usually 1 / 44100s on the time axis) to the corresponding values of the sine wave with frequency of reference standard. ![]() Frequency comparison algorithm is based on calculation of the Fourier transform. Checks each of the frequencies and remembers this, which are most congruent to the frequency received by the microphone. 10/10 recommend.The tuner works by comparing the frequency of the sound from the microphone of Your computer to the sounds of the chromatic scale (c, d, e, f, g, and h). I used to not want to play my guitar because tuning it was such a pain, but then I got this app and now it’s SO fast! I'll be with people and I’ll tune my guitar with this app then they go “woah that was fast!”. I love how easy it is to tune and find and play my favorite songs. I like all the other little games as well because they teach you how to play different chords and you can learn to identify the chords by listening to them and it is all offline. It tunes your guitar accurately so you can get the best sound. I love it! Thanks for making an awesome app. Not only is it a tuner (best app tuner I've used personally) but it also has a metronome, games, chords, and a plethora of instruments to choose from and it's SUPER easy to navigate. Overall, it's a great app for beginners and is a wonderful resource for a pretty reasonable price. It also has a large selection of songs to play along to and it helps show you which chords to play as well how to make the shapes with your fingers. I mostly use this for tuning my guitar, which this app makes ridiculously easy. This is a great app! Very easy to use and very reliable, if you are just starting out, you can take a big worry off your mind, by getting in tune quickly and easily with this app. Easy to use, super user-friendly and they have a bunch of fun different chords and songs to help you learn new music. I’ve downloaded many tuning apps before and this one is by far the best.
