Why do we use 48kHz sample rate?
Re: Why a sample rate of 48kHz??
Same here, working at 48kHz to avoid aliasing without increasing the CPU load too much. Working at higher rates also creates more intermodulation distortion, so that's pretty useless. 44.1kHz is just too narrow for the slope of the anti-aliasing filter.
Is 48000 Hz sample rate good?
In digital audio, 48,000 Hz (also represented as 48 kHz, or DVD Quality) is a common sampling rate. It has become the standard for professional audio and video. The DVD format uses the 48 kHz sampling rate, and its doublings.
Is 48000 or 44100 better?
The main difference between 44100 Hz and 48000 Hz is the audio quality. The 48000 Hz sampling rate offers greater resolution and detail in music. This means that music recorded at 48000 Hz has more information in each audio sample, resulting in better audio quality.
What is the sample rate of 48000?
48,000 Hz (48 kHz) is the sample rate used for DVDs so if you are creating DVD audio discs from your Audacity projects you may prefer to work with this setting.
Should I use 48kHz or 96kHz?
In those cases, a 21 microseconds resolution may be more than enough - corresponding to 48kHz. Only for controlled listening situations - with perfect acoustics, perfect speakers and a single listener in the perfect sweet spot, is 96kHz worth going for.
Why is 44.1 kHz not 40khz?
The short answer is - filtering. Sounds in the real world have frequency content right up to 50kHz. So to sample them at 44.1 kHz the Nyquist Theorem requires everything above 20kHz to be filtered out.
Why 48k for video?
Most digital cameras are probably going to offer you a variety of different sampling rates. To avoid being caught out with poor audio recordings that sound muffled, set your camera to 48kHz and leave it there. This will always ensure high quality, full-frequency sound when you're shooting.
Is 24bit 48000hz good?
Anything higher in either parameter is better. So no, it is not best, but good enuf. So, 24 bit at 48k will be better than CD. Having said that, CD already sounds pretty good to me.
Is 192000 Hz better than 48000hz?
Yes. If you have a good recording and DAC, there's more detail in the 192khz audio.
Is it bad to convert 44.1 to 48?
Thank you in advance! TL/DR conclusion: While you CAN change from 44.1k to 48k, your original . wav files will NOT be affected unless you 'Export Stems'. For the cleanest project you'll always want to START your project in 48khz as to not rely on upsampling/converting/timestretching.
Is 48k good audio quality?
48k is just fine! And even if it isn't technically perfect, the mix work is still going to be 99.99999% of the final sound. And you'll probably make a better mix if you aren't fighting with your computer!
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.
Can you convert 44.1 kHz to 48kHz?
To change the sample rate of an audio file from 44.1kHz to 48kHz, you will need to use an audio editing software. Here are the general steps to follow: Open your audio editing software and import the audio file you want to change the sample rate of. Locate the settings for changing the sample rate.
Which sample rate is best?
88.2kHz. This is now the gold standard for hi-res recordings. Using this sample rate produces less distortion (called 'aliasing') when converting from analogue to digital and allows greater freedom when mixing and mastering.
What is the difference between 48k and 96k sample?
Finally, the last downside is that higher sample rates produce files that are significantly larger than lower sample rate files. Going from 48 khz to 96 khz will double your file size. But with file storage getting cheaper and cheaper, this is becoming less of a problem for many people.
Is 48 KHz good enough?
For most music applications, 44.1 kHz is the best sample rate to go for. 48 kHz is common when creating music or other audio for video. Higher sample rates can have advantages for professional music and audio production work, but many professionals work at 44.1 kHz.
Should I use 44100 or 48000 for podcast?
There are circumstances where it can be beneficial to use a higher sample rate but for a final export we believe 44100 Hz to be ideal and the perfect podcast sample rate. 48000 Hz is also a good choice as lots of professional audio equipment runs at that frequency and it would be detrimental to downsample it.
Can humans hear 96kHz?
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).
Is CD quality 16 or 24 bit?
CDs, for example, are only standardised at 44.1kHz/16bit while the most commonly used High-Res Audio specifications are 24bit/96kHz and 24bit/192kHz, providing a noticeable improvement in sound quality.
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.
Is 192 KHz better?
One of the large advantages that was taught to me in audio school that you will benefit from 24 bit 192 KHz as a creative tool if you will be compressing to lossy files after the fact, and also if you intend to change the pitch or speed of what you are working on, and various other plugins you may use that can benefit ...
Is audio for video 44.1 or 48?
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.
What is the difference between 44.1 and 48 for video?
Music is typically distributed at 44.1kHz, so if you're distributing on CD or for online music streaming services, 44.1 is the way to go. 48kHz is typically used for audio recorded for video, so if you're recording something that will be synchronized with video, record at 48kHz.
What is the sample rate for film?
Audio for film and TV broadcast should always be recorded at 48 kHz or one of its variants, 48.048 kHz and 47.952 kHz. If you have been instructed to shoot at 48.048 kHz or 47.952 kHz, always select the 'fake' stamped sample rates of 48.048F or 47.952F respectively unless otherwise instructed by pre-production.
Is 16bit 48000Hz good?
But what is the maximum quality of your headset on another PC? as 16bit and 48000Hz quality is a standard and very acceptable quality for headsets.
Is 24bit 192kHz better than 320kbps?
The highest quality MP3 has a bitrate of 320kbps, whereas a 24-bit/192kHz file has a data rate of 9216kbps. Music CDs are 1411kbps. The hi-res 24-bit/96kHz or 24-bit/192kHz files should, therefore, more closely replicate the sound quality the musicians and engineers were working with in the studio.
Does 192kHz sound better than 48khz?
48khz: mids are very hard, top end was muffled. 96khz: Immediate noticeable difference from 48khz. Cleaner highs, mids are softer and smoother, bass is tighter. 192khz: Top end very airy, the "metallic" tone of the steel strings comes through.
Is 20000 Hz Loud?
The 'normal' hearing frequency range of a healthy young person is about 20 to 20,000Hz. Though a 'normal' audible range for loudness is from 0 to 180dB, anything over 85dB is considered damaging, so we should try not to go there. As we age, it's the upper frequencies we lose first.
Is 16 bit 44.1 kHz audio good enough?
For most purposes, yes it is. Thought of another way, the above spec is called Red Book Audio, and was the original CD specification and is at 1411 kbps. MP3s, even at top quality, only have a bit rate of 320kbps. Thus the now 40 year old CD spec is actually better quality than most people listen to their music at.
Why 44.1 kHz?
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 48khz better for video?
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.
Should I bounce at 44.1 or 48?
5) The Bounce process should specify 48KHz, not mandatory by the Project should be set to 48KHz, too. The issue with video is it is measured in frames, audio is measured in samples. Video interprets audio samples at 48KHZ per second. If you give it 44.1 it will still interpret it as 48 and it will in be retimed.
Does 48khz use more CPU?
- There is slightly less latency at 48khz, but it uses more CPU... - The more I work at 48khz the more I am creating a mismatch of stuff. Now many of my own personal samples are 48khz because I have been working at that sample rate.
Is 48000 Hz good for streaming?
48000 hz is the highest supported sample rate. Sample rates above this are unsupported and can cause a failure in the stream or recording. Most production equipment will work at either 44100 hz or 48000 hz. It is recommended you match the sample rate of your stream with the output of your production equipment.

How many kHz is tidal?
Lossless audio tracks can be streamed to most wireless speakers over Wi-Fi — but the level of these lossless audio tracks is limited by the wireless speaker. For example, all Sonos speakers support lossless audio tracks up to 24-bit/48kHz. Apple's HomePod and HomePod mini also support lossless audio up to 24-bit/48kHz.
Is 48kHz lossless?
Spotify's maximum song quality for streaming is 320kbps [1]. Spotify streams its music at this bitrate, which is slightly lower than the 1,411kbps audio quality of a CD [2].
Is Spotify quality 320kbps?
HiRes FLAC is the distinction we make for any Free Lossless Audio Codec (FLAC) file that is greater than 16-bit, 44.1 kHz, which is the standard CD quality. HiRes FLAC on TIDAL can deliver superior sound in files as large as 24-bit, 192 kHz.
How many kHz is FLAC?
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.
Is 48kHz 24 bit?
That choice is largely a matter of your “target” format. 48kHz for DVDs, and 44.1kHz for CDs. Ultimately, CDs will be 16 bit depth. But, even for CDs as a target, using the 24 bit depth, will give your tracks much better resolution, allowing for much better Mixes.

What is 48000 Hz audio?
48 kHz is another common audio sample rate used for movies. The higher sample rate technically leads to more measurements per second and a closer recreation of the original audio, so 48kHz is often used in audio for video which usually calls for a big dynamic range.
What is 48k sample rate?
Like a live recording with tons of percussion and rich breathy vocals and a lot of room ambience, you might be able to hear more aliasing at 48 rather than 96. Beyond that, 96 takes up twice the drive space, and twice the streaming bandwidth! It is easier to implement an — inaudible — anti-aliasing filter at 96 kHz.
Is 96k better than 48K?
If you're doing ANY pitch shifting or time stretching, even just slight to moderate amounts, 96k vs 44.1 and/or 48 makes a huge difference. And this is the only time anybody really should be using 96k+ sample rates.
Is 96k sample rate worth it?
Proponents of 96kHz, in fact, point to studies on converter performance at higher sample rates, localisation information in audio streams, and bring out the one argument no one can refute: “It sounds better to me.” Whether it's the placebo effect, hearing acuity, or some as yet unquantified technical issue, some ...
Why use 96kHz sample rate?
48k is just fine! And even if it isn't technically perfect, the mix work is still going to be 99.99999% of the final sound. And you'll probably make a better mix if you aren't fighting with your computer!
Is 48k good audio quality?
However the truth is that studies show most people over the age of 30 cannot hear anything above 17 KHz and this reduces further as you get older. Yet people reliably report that high sample rates like 88.2 and 96 KHz sound better than 44.1 and 48 KHz.
Can humans hear 48 KHz?
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.
Is 48000 Hz better than 44100 Hz?
44100hz sample rate is enough to reproduce well above the highest frequency even young humans can hear, and 16 bits of depth is enough for 96db of dynamic range, enough to make the noise floor of any consumer system totally inaudible.
Is 44100 Hz enough?
The commonly stated range of human hearing is 20 to 20,000 Hz. Under ideal laboratory conditions, humans can hear sound as low as 12 Hz and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea.
Can humans hear 200000 Hz?
The response of the ear is governed, in part, by the mass and elasticity of the eardrum, muscles and ligaments, bones, and fluid and structures in the inner ear. Elasticity opposes low frequency sounds, while mass opposition increases as frequency increases. So both mass and elasticity set limits for frequency range.
Why can't humans hear above 20000 Hz?
The Flac file uses 24 bits per sample instead of 16 bit for the CD and uses 96khz sample rate instead of 44.1 khz on a CD.

Is 48 kHz good enough?
44.1 kHz vs.
48 kHz is another common audio sample rate used for movies. The higher sample rate technically leads to more measurements per second and a closer recreation of the original audio, so 48kHz is often used in audio for video which usually calls for a big dynamic range.
Should I change project sample rate to 48 kHz?
In the US, these video recorders ran at 30 frames per second and had 490 useable lines per frame (excluding blanking lines). It was decided that 3 audio samples should be stored per line of video. 3 samples per line X 490 lines X 30 frames per second. This gives us a total of 44,100.
