An audio frequency (abbreviation: AF) or audible frequency is characterized as a periodic vibration whose frequency is audible to the average human. The SI unit of audio frequency is the hertz (Hz). It is the property of sound that most determines pitch.
The generally accepted standard range of audible frequencies is 20 to 20,000 Hz, although the range of frequencies individuals hear is greatly influenced by environmental factors. Frequencies below 20 Hz are generally felt rather than heard, assuming the amplitude of the vibration is great enough. Frequencies above 20,000 Hz can sometimes be sensed by young people. High frequencies are the first to be affected by hearing loss due to age and/or prolonged exposure to very loud noises.

Sinusoidal wave going trough entire human audio spectrum, starting at 20Hz and ending at 20kHz. Note that the frequency increases exponentially, the idea was to increase the frequency by constant fraction of currently played frequency rather than by a constant value (which would result in clearly noticeable fast change at lower frequencies and nearly no change at higher frequencies). Enjoy. Note: This wave has the same volume level measured by acoustic pressure all the time, however human sound perception differs depending on frequency. For lower frequencies (below 1kHz) you might want to increase your volume, but don't forget to lower it later to avoid damage to your hearing. If you don't hear anything below 40-50Hz even at full volume your audio hardware is probably incapable of playi...
In a nutshell, CDs chop off all the audio content above 22 kHz, while LPs roll off smoothly up to 60 kHz and beyond. Considering that the upper limit of human hearing is commonly agreed to be only 20 kHz, it is up to you to decide how much of a difference this actually makes. But the use of high digital sampling rates lets us record and visualize these upper frequencies which even the current 96 kHz/24 bit standard for professional audio cannot fully capture.

Hearing Test in HD quality. Sinusoidal wave starting at 20 Hz frequency and going up to 20 kHz frequency. It's recommended that you listen to this using headphones. If you can't hear anything above 16000 Hertz it's probably because Youtube's audio compression cut off frequencies above 16kHz. Try watching in HD to get better audio quality.

his track is designed to stimulate the Sacral Chakra. The 2nd Chakra (the Sacral Chakra) relates to our ability to feel creative, sexual, and accept change. Here's what you need to know about Sacral Chakra healing. Location: Lower abdomen, about 2 inches below the navel and 2 inches in. Emotional issues: Sense of abundance, well-being, pleasure, sexuality. The frequency within this audio masking focuses on releasing the necessary triggers through means of finely tuned vibrations which in turn inaugurate the fundamental structure of the Sacral Chakra, leading to rejuvenation and where required - healing. Listen to this track as much or as little as you feel comfortable, either sitting or lying in a settled position. We always recommend using headphones for optimal results, however this is...

http://www.homebrewaudio.com - What does EQ mean? Well, it stands for "equalization." But what does THAT mean? Well, first you have to know what frequency means? Sigh. These things are usually not explained very clearly - at least not so that anyone (not just audio engineers or techies) can understand. But this video should fix that. The concepts are not hard. But they are usually explained so poorly that they SEEM hard. After watching this video, you will finally really understand what EQ means and how you can use it to improve your audio recordings. It (this video) is an excerpt from the newly updated tutorial course - The Newbies Guide To Audio Recording Awesomeness 1: The Basics With Audacity.

This is my response to the video at https://youtu.be/4eC6L3_k_48 . So...what happens if you take a vinyl record that was mastered on all digital equipment in 1985 with a known master recorder frequency response of 20 to 20,000kHz (16bit@44.1 or 48kHz) and look at the frequency spectrum? You'll see it here. Remember, it is impossible for there to be frequencies above 20kHz on this due to the session and master recordings. Impossible, that is unless there is something being introduced to the playback. While true that it is possible to have frequencies above 20kHz on a vinyl LP, most of the time, that's wasted noise that you can't hear. Vinyl - like the CD - was engineered for 20 to 20,000Hz and the RIAA curve ends at 20,000Hz. (There were exceptions for CD-4 quad LPs using a 45,000Hz...

285 Hz is the Frequency of quantum remembering, remembering we are a soul having an earthly experience. People like to say that we are only human due to the mistakes we make and what we perceive to be failures.
