(1.6) Doubling Frequency. Something very interesting happens when you double the frequency of a note. The pitch of the doubled frequency sounds higher, but somehow the same as the original note, while the pitches of all frequencies in …

Audio frequency doubling, I use a double diode "full wave" method off of an OP amp output for "higher frequencies > 400 hz". It works great for a musical sound but would distort the true sound reproduction you are trying to capture. For fun here is a sub-harmonic "Whale call" generated from my own design of a two transistor theremin.
audio - Pitch Detection: avoiding frequency doubling ...
https://dsp.stackexchange.com/questions/17758/pitch-detection-avoiding-frequency-doubling-halving
However, when I compare to other tuner apps, I seem to be getting frequency doubling on certain notes with certain instruments. Sometimes frequency halving depending on other factors. I have tried adjusting the buffer size (size of array of samples) and also the sampling frequency. Algorithms include: Auto-Correlation, YINFFT, Dynamic Wavelet.
Understanding Frequencies in Audio: Getting Perfect …

Audio Fact: If we double the frequency of a musical note, we end up with the same note, one octave higher. This means that we hear logarithmically – the doubling in frequency (pitch) between 120Hz and 240Hz feels like the same jump in pitch between 3kHZ and 6kHz.
4 Tips For Doubling Instruments (+ 3 ... - Pro Audio Files

Another great use of doubling is adding weight to instruments by stacking them with doubles with complementary frequency content. If the original sound feels thin, pair it with a double that helps add body; if it feels muddy or indistinct, layer a …
Frequency doubling, explained by RP Photonics …
https://www.rp-photonics.com/frequency_doubling.html
Frequency doubling is a phase-sensitive process which usually requires phase matching to be efficient. This means that the second-harmonic field contributions generated at different locations in the nonlinear crystal coherently add up at the crystal's exit face. With proper phase matching and a pump beam with high intensity, high beam quality, and moderate optical …

Doubling the sound pressure (voltage) corresponds to a measured level change of +6 dB Doubling of sound intensity (acoustic energy) belongs to a calculated level change of +3 dB. +10 dB is the level of twice the perceived volume or twice as loud (loudness) in psychoacoustics − …
How many dB (decibels) represent a doubling or halving …
https://www.quora.com/How-many-dB-decibels-represent-a-doubling-or-halving-of-the-sound-volume
Answer (1 of 5): That’s a relatively complex issue. 3 dB is a doubling of power 6 dB is a doubling of voltage or sound pressure level (SPL) 10 dB is considered to be, to humans with a non linear sense of amplitude, a doubling of apparent loudness.
