Why is sampling frequency 44100?
Analog audio is often recorded by sampling it 44,100 times per second, and then these samples are used to reconstruct the audio signal when playing it back. The 44.1 kHz audio sampling rate is widely used due to the compact disc (CD) format, dating back to its use by Sony from 1979.
Why was 44100 chosen?
Recording on video equipment
44.1 kHz was deemed the highest usable rate compatible with both PAL and NTSC video and requiring encoding no more than 3 samples per video line per audio channel. NTSC has 490 active lines per frame, out of 525 lines total; PAL has 588 active lines per frame, out of 625 lines total.
Why is music 44.1 kHz?
The Origins Of 44.1kHz
It is known from Nyquist's Theorem that in order to reproduce any given audio frequency, the sample rate has to be at least double the highest frequency you wanted to reproduce. This meant that CDs had to sample at a rate of 40kHz or higher in order to cover the audible frequency spectrum.
Is 44100 Hz good?
The sample rate of 44100Hz is standard for music and CDs and is the ideal rate to record all your podcast audio at.
Is 48000hz better than 44100?
The sampling rate affects the audio quality of digital music. A higher sampling rate like 48000 Hz allows for greater resolution and detail in music. This means that music recorded at 48000 Hz sounds clearer and more detailed than music recorded at 44100 Hz.
Why is using a sampling frequency of 44100hz important?
One reason may be that human hearing roughly ranges between 20 and 20000 Hertz. Hence, 44.1 kHz is a logical sampling rate to capture the full (human) hearing range (Nyquist theorem). You can always use higher sampling rates and downsample afterwards. Just needs more storage.
Is 192KHz better than 44.1 kHz?
As an example, a 16-bit 44.1KHz CD has 28,901,376 potential sampling points each second and a 24-bit 192KHz recording roughly 256 times the resolution of a 16-bit 44.1KHz recording.

With a sample rate of 44.1 you can display frequencies up to 22kHz, higher than you probably can hear. Also 16bit has a possible dynamic range of 96dB, that's pretty much the range between the quitest noise you could possibly hear and painful noise.
Is 320kbps the same as 44.1 kHz?
44.1 kHz and 320 kbps are two different specifications that describe the quality of audio recordings. 44.1 kHz refers to the sample rate of the audio recording. The sample rate is the number of samples taken per second to represent the sound wave.
Is 44.1kHz high quality?
High-resolution audio (high-definition audio or HD audio) is a term for audio files with greater than 44.1 kHz sample rate or higher than 16-bit audio bit depth. It commonly refers to 96 or 192 kHz sample rates. However, 44.1 kHz/24-bit, 48 kHz/24-bit and 88.2 kHz/24-bit recordings also exist that are labeled HD Audio.
Should I use 44.1 or 48kHz?
In some cases, such as audio-for-video work, you'll generally want to stick to 48kHz or 96kHz for best compatibility with video requirements. For CD release, 44.1kHz is still the standard, though working at higher rates and sample rate converting the audio down to 44.1k is always an option.
Why is sample rate 48000?
Ultimately, they chose 48 kHz, because there would be a leap frame every 5 frames, unlike 50 kHz, which would have a leap frame every 3 frames of color and b/w NTSC video, because European television was already using 48 kHz, and because it was easy to synchronize with 24 frames per second, a common frame rate used in ...
Can humans hear 44.1 KHz?
The range of human hearing is 20 Hz to 20 KHz. A 44.1 KHz sample rate (the sample rate of audio CDs) does reduce the high frequencies a little bit above 18 KHz. Higher sample rates do preserve these ultra high frequencies. Even a 48 KHz sample rate can represent frequencies up to 20 KHz (the limit of human hearing).
What bitrate is 44100 Hz?
44,100 Hz (44.1 kHz) is the sampling rate of audio CDs giving a 20 kHz maximum frequency. 20 kHz is the highest frequency generally audible by humans, so making 44,100 Hz the logical choice for most audio material.

Why use 96kHz sample rate?
Higher Sample Rate Benefit #1: Can capture higher frequencies. Higher sample rates allows us to capture higher frequency data above 22.05 kHz. In fact, if we sample at 96 kHz, we can reproduce audio signals as high as 48 kHz, which is more than twice as high as humans can hear.
Can humans hear 24-bit audio?
In the human auditory system, the threshold of hearing is 0dB SPL, whilst the threshold of pain is around 120dB SPL. As such, the 144dB of dynamic range that 24 bit offers is already high enough to capture sounds lower than we can hear and louder than we can tolerate.
Is 32-bit DAC better than 24-bit?
A 24-bit audio sample can represent up to 16.7 million levels of amplitude, while a 32-bit audio sample can represent over 4.2 billion levels of amplitude. In practical terms, this means that a 32-bit digital audio recording can capture a greater dynamic range than a 24-bit recording.

Does 96kHz sound better than 44.1 kHz?
96kHz audio takes up over twice as much memory as 44.1kHz audio. Running at 96kHz stresses out the computer more and reduces the potential track count. It may not make any sonic difference anyway.
Which is better 320kbps or FLAC?
How noticeable is the difference between FLAC and regular 320 kbps MP3 to a normal user? MP3 is limited to 48′000hz sample rate, while FLAC is not. So, not only is FLAC lossless, it can also have higher resolution. 320bkps MP3s are very close to lossless “CD quality” audio.
Is FLAC better than CD?
FLAC, first introduced in 2001, is opening up a whole new world of high-end, high-resolution audio for enthusiasts: 24-bit digital has a theoretical resolution of 144dB (compared to around 96dB in CD's 16-bit) which is more than enough, given that 130dB is the threshold of pain for the human ear.

FLAC, or Free Lossless Audio Codec, is a popular digital audio format where files are compressed without losing data or quality. FLAC files are generally encoded at a bit depth of 16 or 24 bits and a sampling rate of up to 192 kHz, which makes them ideal for high-quality audio playback.
How many KHz is FLAC?
The others played fine, and I found that while I could not discern an immediate difference between the two Bit Depths with my headphones, there was a HUGE difference between 48000 and 192000 Hz. Zebra 2 sounded amazing at 192000Hz - very full and sounded like it was resonating.
Is 192000 Hz better than 48000?
I think most of us can agree to that. Any identical 96khz session is going to sound immediately better than a 48khz session. But when it comes to comparing mixed down and bounced material that are sampled down to 44.1 from any higher frequency, i find it becomes much more difficult to discern between the 2...
Is 96kHz better than 48kHz?
You can change the project rate back to 44.1kHz, in which case your exported file would match the project rate setting. If you don't have any specific requirements leave it at 48kHz and avoid any unnecessary conversions. The conversion wouldn't affect the sound but if there's no reason it's best not to do it.
Should I export at 44100 or 48000?
The main reason is that 48kHz gives enough headroom to catch most higher frequencies on the audible spectrum. Also, 48000 is divisible – 24, 25, 30 and for interlaced television 50 or 60. These are common frames per second increments used in film production.
