3. Common Audio Sample Rates - Digital Audio Fundamentals

[@kevinwydler7305]

Thank you so much! As an upcoming audio engineer, I can not overstate how important this topics are to me and you manage to explain them so clearly and exceptionally well!

[@charliexu5013]

Your videos are super hardcore ! We really need more of this ! Thank you very much!

[@akashmurthy]

Cheers bud! Will try to keep making more!

Hey, your work is amazing man! Love to watch your videos, keep it up!!

[@akashmurthy]

Thanks very much man!

[@station2station544]

Love reviewing these videos. Haven't heard this stuff since I took Audio Sweetening in college in the 90's

[@soumoyadipsamanta3252]

this is pure next level explanation...why i am finding this just the day before my exam?

[@akashmurthy]

Thanks very much! Glad you found the channel..

[@bil63]

Thank you! Very clear and simple to understand! Waiting for new videos :)

[@akashmurthy]

Thanks! New one coming up in a week.

[@MerajTypeBeat]

Wow, these videos are top notch and well put together, explained and produced. Deserves way more attention! 💯 You definitely got a new fan. Subbed!

[@akashmurthy]

Thanks a lot mate!

[@mdxggxek1909]

This is such a cool serie

[@akashmurthy]

Thanks mate!

[@sahiltakbhate]

Very informative! And the visuals were just amazing and on point!

[@akashmurthy]

Thanks for checking it out mate!

[@briangitonga6909]

Thankyou so much for these videos. The editing, the way you are explaining it. Just pure bliss. I'm really new to this whole thing and I'm trying to make an app the uses a range of different frequencies. So these videos are a really great help to make me understand how sound works behind the phone. Question - What is the name of the app that you used to create the frequencies at 8:06?

[@akashmurthy]

Thank you for the feedback! I'm glad you found this useful. Regarding the app I used, I'm not sure to be honest. I don't have it on my phone anymore. But it's just a generic frequency ramp or sine sweep. If you Google those terms for Android apps, you should be able to find it.

[@abhinavswynenberg]

Very nicely put Akash, Thankyou for putting in so much effort

[@akashmurthy]

Thanks you! I enjoy doing this!

Really fantastic explanations of these concepts! Super clear and simple, but still with lots of depth in a subject that's so often misunderstood. Just an FYI, KZbin is hard-coded to 44.1kHz and bandlimits all audio to 16kHz, though I think you're right that 48kHz is very common in other video applications. I know most streaming services also use compression and variable bitrate encoding though, and that's something I'd love to know more about, especially in terms of how different types of compression affect quality. Maybe material for a future video?

[@akashmurthy]

Thanks for the feedback mate! And for the info on KZbin's spec! I think you've got plenty of knowledge and interest in that area, but as for me, I'm not particularly good at media delivery and objective analysis of different types of compression on quality, and stuff like that. Since my free time is limited, I hope to focus more on the DSP side of audio, where my speciality and interest lies..

[@memeswillneverdie]

Yes it’s 44.1 but it’s not limited to 16khz, look up a Dan worral video on it, it’s really well explained but essentially it’ll only use that severely band limited version to save bandwidth but most of the time it’s using opus 251 right click on KZbin and go to stats for nerds and look at the audio it should say opus, meaning it’s not limiting it

[@sanjoghamal1457]

Thanks for the video, It's amazing

[@akashmurthy]

Thanks for checking it out!

[@orsogrande8313]

Excellent!

[@nayananandvats2171]

Great video. Also, would be great if you can suggest one book that every Audio engineer should read. Cheers :)

[@joshuadaniel3289]

Thank you so much for the series, Akash! They are super helpful! On the topic of sampling rate, just curious to know how 44.1k or 48k became a standard. Why not 42k or 43k, or 49k or any other? Why exactly 44.1k and 48k?

[@akashmurthy]

You're welcome! As I had briefly mentioned in the video at 12:22, the sample rates were chosen to work well with current standards of the day and the requirement to keep the mathematical conversions as simple as possible to avoid loading up slow processors of the day. You can read up on it more online, it's an interesting read.

@@akashmurthy Thanks man! Really appreciate the effort!

[@markocvejic6416]

Amazing content, Im junior engineer working for a company that works for dolby atmos. Your videos are superb! And graphics also! I really like the graphics in the video, what kind of software are you using for them, do you make them or someone else?

[@akashmurthy]

Thanks man! Interesting! What do you work as, electrical or software? I use After Effects for the animations, and yea, I make them myself.

[@markocvejic6416]

@@akashmurthy I work as software enginner. Basically we do certification of dolby atmos software, and implement it on a real hardware like soundbars. They write a bunch of c++ code, we translate it into assembly for dsp to use. Do bunch of testing, send back for certification :)

Sir, are DSDs and MQAs are just the placebo...? great videos btw :)
