You are most likely experiencing the non-linear frequency reception of the human hearing and the frequency response in your playback system.
As listener you perceive a constant loudness of steady tones roughy following this chart (Equal loudness contours or "Fletcher-Munson" curves):
In addition your headphones or speakers frequency response curve is also ...

Drum tuning is largely dependent on the style of music being played. A jazz kit will usually be tuned to exact pitches in a scale, such as the snare being tuned to the root, one tom tuned to the fifth, one to the third, one to the root an octave lower, etc. A jazz kit will also usually be tuned such that the top and bottom heads are in tune with each other....

I think you've misunderstood what Frequency is, with respect to audio. Whilst 'Frequency' typically is 'how frequently something occurs', in audio it's how many times a sine-wave oscillates in a second, rather than how many things you hear in a second.
eg. A standard kick-drum track at 60 BPM means you'll hear a kick-drum sound once-per-second. That actual ...

Two thoughts...
1) The song is currently in the wrong key for the sound you are aiming for, vocally. The only fix for that would really be to re-record it in a more suitable key.
2) There are plugins available that can adjust the formant** of a sound without changing the pitch. Probably the best tool available for that is Melodyne [imho] which can adjust ...

As you mention that you have experience in programming, the Essentia library might fit your need.
Essentia is an open-source C++ library for audio analysis and
audio-based music information retrieval released under the Affero
GPLv3 license (also available under proprietary license upon request).
It contains an extensive collection of reusable ...

There is a VERY simple way to do this, as I have needed the exact same effect before.
Click in an empty plugin window, go to Audio Units > Apple > AUpitch
this will allow you many many semitones of pitch shift with the ability to automate smooth changes. Hope this helps

No it isn't; neither is it possible in wavelab or any other piece of software I've come across. Maybe someone out there knows differently?
What you are asking about is the ability of software to detect (sometimes) very subtle changes in pitch. Vocal pitch changes are not uncommon even for the most perfect of singer and it is the human brain that ultimately ...

The generic term for this is vibrato, though it wouldn't usually move 'between octaves' but rather in smaller increments like semitones.
Applying a low-frequency oscillator to the pitch pin on a tone oscillator would achieve the effect. The amplitude of the LFO would control the degree of pitch shift over time, and its frequency would affect how rapidly it ...

The sox utility can do this. To generate a WAV file:
sox -n output.wav synth 600 sine 20-16k
Mind you, this will generate a 100 MB WAV file, since it defaults to a 48 kHz sampling rate. Since you need a maximum frequency of 16 kHz, you could get away with a 32 kHz sampling frequency instead:
sox -r 32k -n output.wav synth 600 sine 20-16k
This file will be ...

Sounds like you're looking for an arpeggiator.
With some plugins, you can either program a step-sequenced arpeggio, which triggers on a MIDI note event.
These will mostly be atonal/chromatic, and won't necessarily adhere to any scales that you're using. There may be some that have this intelligence however.

Processing has good sound libraries such as Minim and apparently a new factory library check this link.

Firstly it's nice to see someone making use of RS5000! Sadly, though, it works in the same way as most samplers in that it achieves the pitch changes simply by playing back the sample data at different speeds.
Within Reaper you could do the work using ReaPitch which would also allow you to do formant correction to compensate for the vocal sounding ...

There is no 100% certain way to determine which equal-tempered scale standard was used as tuning basis for a song. However the vast majority is A440. Many electronic instruments don't really give you any choice.
However you ask how to determine it. You'll need to do a spectrum analysis and sum up the energy around the fundamental frequencies of the scales. ...

There‘s a tab where you can set the algorithm. Usually setting it to „melody“ should fix this.

In the most basic form of pitch-shifting, we play a sample faster or slower. This has some side effects along with the desired pitch shifting - the duration and the formant of the sound are also shifted.
In your case, like Thomas already mentioned, it is the shifted formant that causes the squeakiness.
A formant is formed by the resonances inside a ...

The smallest interval a human can hear depends somewhat on the register and timbre of the tone (and it varies from person to person), but generally speaking the smallest detectable difference is around 5-6 cents, according to this study from 2006:

It's going to be difficult to come up with an absolute number, because it will vary greatly between individuals. I suspect it will also vary with age, exposure to music, and any number of other factors.
That being said, this question has been asked on some of our sister sites:

Take a look at Praat which has spectral and pitch analysis built in.
Here is a video explaining how this is done.

Like said in the comments, the fist thing to do is to separate the frequencies we want to affect from the rest. This can be done using LPF/HPF combo to form a BPF (I find it easier to set my cutoff frequencies using 2 filters rather than a BPF because with BPFs you have a center frequency and bandwidth (Q) which requires some calculations to figure out the ...

There are a lot of questions here:
Is this just a single note with a pitch modulation e.g. with an lfo?
Looks like an arpeggiator with different notes.
How would the curve look like?
If you are talking of the modulation (second part of the sound) , I would say a sineshaped LFO that modulate a parameter (which one I don't know, perhaps a wabetable)

It's simple really; Your speakers can't reproduce a 1Hz sinewave, and if it could, you wouldn't hear it due to the limits of human hearing(plus, due to the size of the speaker cone, it would have very little energy).
If your speaker could reproduce a 1Hz sinewave, you would see the speaker cone moving in and out with a one second period. If you were to play ...

There is:
Surfer Eq by Sound Radix:
http://www.soundradix.com/products/surfer-eq
EDIT:
Just clarification on the plug-in: It bases the EQ curve on the fundamental pitch of the source material, so it will shift in response to changes in pitch. Meant mostly for instruments or tonal material (music) but also useful for sound design.

While not related to Audacity, AutoTune can tell if you are slightly out of tune and even correct for being slightly out of tune, however that is the limit of what I know of for correction. It wouldn't be able to match to a sample if the sample wasn't in tune though I don't think.
Being off rhythm should be pretty obvious without a plugin as one sound ...

I know i'm a year late, but hopefull this will still help someone. I found a little VST today called Son of a Pitch. It's free and pretty darn good even if it is kind of hard to catch on as to how to work it at first, but it has 3 octaves up or down that you can adjust to your liking and it's automatable. After installing it though, don't look for son of a ...
