usually companies only makes youtube videos advertising their products, but this one makes hidden gems of tutorials... after watching a lot of tutorials i finally understand what the heck are bit depths and sample rates because of this. thanks

you're like a voice actor... your voice sounds so gentle and sort of mesmerizing. it must have something to do with the knowledge of how to use sounds properly. Thanks for the clip!

Though I already knew what sample rate and bit depth are, I found something new to me here. Thank you!

Good job explaining these concepts. Not too much information and not too little.

Excellent video! Aliasing is a tough topic for me atm, but I'll research it elsewhere now

this dude talking in chunks is GREAT

Ahh so record everything at 10Mhz, got it! Great video.

The quality you put into this video is amazing! Thank you so much!

I had to learn the differences between sample rates and bit rates for uni and this helped me a lot! Thank you!

Excellent video. Didactic, direct and easy to follow. Thanks, that's how you really learn.

great content beautifully structured for easy understanding. I'm a big fan of educators, not reviewers and other BS. audio trumps video always, without sound video generally sucks. just mute any video and see how long you'll keep watching. now i can up my audio wiht a better understanding of analyser in garage band and other tools.

Great video brother. This helped a ton with my editing.

I taught my production students about this just yesterday.

Excellent video. Very lucid! Thank you.

Excellent. Thank You.

Very nicely explained Sam

Excellent explanation!!

I see. In videography term, sample rate is like frame per second. Traditionally, cinema is 24fps, while modern video can be 30 or 60 fps. If you want slow motion, then you can capture video in 120 fps and play it back at lower fps. If you capture video at 120fps and play it back at 60fps timeline, you will get 2x slow motion. If you play it back at 30fps, you will get 4x slow motion. And if you play it at 24fps, you will get 5x slow motion without any stuttering or other problems. Exactly because 120fps can be scaled back nicely in those frame rates. While bit depth is equal to..... video bit depth. Video bit depth is based on RGB value. That one is harder to explain but generally speaking 10 bit color will have more value and better dynamic range than 8 bit color. 12 bit have more value than 10 bit and so on. High end cinema camera can record 16 bit color.

Thank you! It is really deep.

Excellent video! ✌

editing is so beautiful

Great way to explain it.

Remarkable work.

very good thank you!

I followed one of your pages and was led here. Most people think that the sample rates and bit depth fully capture the frequency range possible in the sample rate but the truth is that it's only a spectrum/frequency range container/allocated where as the audio capture device also needs the ability to capture the higher frequency range to pass it onto the container to get the full benefit. Most audio interfaces are rated between 20-20khz and will have fall off levels after that (even if advertised 24/192 max sample rate.) I miss my Roland UA-101 (no win 11 driver) Why would "professionals" want higher than human hearing? usually to create ambient tracks and creature voices by recording the highest frequency range they can and then stretch out the audio so the audio is smooth rather than missing frequencies and sounding bit crushed. Another giant factor that many may not realize is that missing frequencies maybe detrimental to your health, all physical matter is effected and shaped by sound - look up cymatics. Sound stimulates cells were as deprivation kills cells - just like a puppy without its mother or father to hear a heart beat, if there is none it dies or develops neurological problems.

Thank you sir

cada vez entiendo un poquito más. gracias por la información 🙏🙏🙏

Thanks man

You're AWESOME 👌 👏

Gr8! Thanks!

thank you

very useful video. You are being watched around the world. Why are there no caption?

Thanks for that informative explanation, Sam -- very easy to understand. One question, tho -- what are they talking about when they talk about a depth of 1 bit depth? I googled for information about the SACD format and it returned this: "While the standard CD format is tied to a 44.1 kHz sampling rate, SACD samples at 2.8224 MHz. Also, instead of a 16-bit depth, it uses a 1-bit depth" this came from Lifewire website. Years ago I also came across a friend's CD player that had emblazoned on the front along with the CD logo, that it was 1bit. If the higher the depth bit number is gives the better performance, what are they talking about when they say 1 bit depth? Wouldn't that mean the audio is right at the the noise floor?

SACDs are based on the DSD file format. To learn more about this, and it's quite a large topic in and of itself, you'll want to research other videos on here that go into detail about the DSD file format.

Great explanation. But for us normal folks, do I need Tidal HiFi Plus, which allows for up to 192kHz/24bit? My sound system can play hi res lossless but if I am not editing the source audio, do I need hi res lossless? Or should I stick with KZread Music?

❤️❤️❤️❤️

Could you help me to understand this. If you are recording at a low input level (let's say you're peaking at -24db) does that mean that you are not using your full bit depth? This should explain why it's so important to record at as high level as possible, but without going so high that clipping occurs of course.

Who knows at what levels of these parameters KZread is outputting it's audio? I have mechanically detected Kbps rates of nominally 126-150, but there are a few that come up above that and a few that are below 100. To be honest it's only during an A-B comparison that I can detect the poverty of a 160 rate compared to CD quality, but for normal listening (with ambient noise from Modems, fridges etc the (high) quality of the loudspeakers I use subjectively far outweighs the quality (depth etc) of the original signal.

Hi Sam, there seem to be two schools regarding which Sample rate to use while recording Voice Over work. I’d like to hear your thoughts. I’m new to Voice Over and the Udemy Voice Over professor I do respect suggests it should without question be 48000 while another You tube Adobe Audition explainer video insists the standard is 41000. I’d like to get a clear understanding of the ‘correct’ or ‘ best’ Sample rate as I’m working hard on developing my career in Voice Over. Thank you for your time!

Hi Cristiaana. Generally speaking, if the VO work is destined for video, then 48kHz is going to be best. If it's going to stay in the audio realm, then 44.1kHz will likely be sufficient. The standard for video is 48kHz and for audio is 44.1kHz, so I guess they're both right in their own way, it just depends on where the VO will end up. Hope that helps!

At 2:07 he says bit depth in audio is "similar to the idea of megapixels in a camera". Not really -- file size in audio is similar to megapixels in a digital image file. Bit depth in audio is similar to bit depth in an image, where bit depth in an image represents the color capacity for a particular image, meaning higher bit depth means finer gradations of reds, grays, etc. Higher bit-depth images of a fixed resolution (pixel dimensions) are more pleasing to the eye compared to a low bit-depth image when viewed on a high-quality display.

what happene if we make 48khz from original file audio mp3 44.1 khz

Do we use clock on bit depth

Now i am incredibly curious to listen to music that has 10 hz sample rate. 10 updates per second, isn't it interesting to listen?

Isn’t bit depth more closer to the cameras concept of dynamic range than resolution?

So is amplitude volume?

I thought to get rid of aliasing you increased the sample rate to twice the range of human hearing

@2:11 No, let's please!

i love the english accent & digital Audio. 😁🤣

I believe however regarding bit depth that it does not equal quality as per the resolution of an image for the audio per say but rather only increased dynamic range and noise floor.

That is completely true but you could argue a very low bit depth will lessen the quality of your audio.

@@davidasher22 why is that ? Can you explain how in theory there is more “resolution” ? A sine is a sine no matter if it’s away from noise floor. Most Mic and preamp does have some noise floor higher than 16 bits.

@@sylvainbiensur7370 seriously? Have you ever listened to audio that was subject to lower and lower bit depth? You start loosing resolution and the lack of samples will start giving you quantization errors that result in digital noise. I would consider that worse sound quality. Granted the frequency response isn’t affected but the sound coming out of the speaker is. Let me put it like this.. What has better sound quality, a new PlayStation or an original Nintendo? Thats the difference between 16 bits and 8 bits. Do you think otherwise?

Lower bit depth does indeed affect resolution but it's really only a problem for extremely dynamic music that was recorded at 24bit such as orchestral that has very quiet passages. That's why music producers use Dithering algorithms. You need Dithering for this kind of material when reducing down from 24bit to 16bit for CD release but you're not going to notice it on a Rock record.

32 float all day! 😁

for me i do 32 bit Depth and 48khz

Mostly good but a bit misleading when you say "you get more precision using 24 bits" compared to 16 bits: The difference is the dynamic range and noise floor... It's important to understand that you won't loose information using 16/44.1 compared to higher sampling rate. Higher sampling rate / bit depth will give you less noise while mixing, it make sense. But for the recording people will get, there's no point providing it with a higher sampling rate / bit depths than CD quality (16 bits / 44.1 KHz). kzread.info/dash/bejne/lX2Fm6uRg7jgpbA.html and the ref. book "Oppenheimer - Discrete-Time Digital Processing"
