Understanding Audio Dynamic Range / SNR (Part 1)

This is a tutorial and demonstration of dynamic range and signal to noise ratio as used in measurement of audio products. Also covered is conversion of such metric into "bits" and why we care. Future video will dive deeper into our needs for dynamic range.

Amir, you're a born teacher. Thank you for taking the time to share your profound knowledge and expertise.

[fcracer]

You’re doing a great public service sir! Many thanks for sharing your knowledge of audio electronics with us in such a clear, concise, and compelling way.

These types of videos are much needed in the "audiophile" community. Many people do not understand that audio gear are electronic devices that can be measured and tested for level of performance and are not some magical things that defy the laws of physics. Seems like a lot of self-proclaimed audiophiles barely understand electrical theory let alone electronics, so these videos should be very helpful for a lot of people.

This channel is the best antidote to audiophile snake oil on youtube 😜👍

Oh man, Really wanted this video explanation from you Amir! Thank you :)

Hi Amir, this kind of videos showing how to understand those "names" are amazing, thanks

[kevinchoi]

Hi, I recently found your video. It is fantastic because I didn’t understand important graphs and numbers. Well, I studied the business administration but I am a music lover, kind of audiophile for 25 years. Therefore, I wanted to understand what the numbers of my gear mean. Thank you so much. I will click every tutorials on basic.

Thank you, I love these vids you are doing on measurements, much needed. They will be a valuable resource when I forget in a year and need to review it all again.

Great video Amir, keep up the fantastic work!

[zyghom]

PERFECT brother! thank you for my "3rd age education" from your channel ;-)

[TTykwer]

I've gone back to school. And I love it! Thank you.

[labalo]

You’re really pumping out content. Thank you.

Dear Amir, I have found your channel a couple of days ago and I am blown by the clarity and quality of your contents. You're the first channel, among the hundreds I have subscribed to, for which I turned the notifications on ! :)

Fascinating. Just discovered the channel last week and the content is superb. I have an engineering background, so I still regard proper test and specification data as important. Just looked at the spec. booklet for my vintage Quad 33 preamp and it DOES give s/n ratio relative to input level. E.g. RADIO : 85dB for 100 mV input level for 0.5 V main output. This tutorial helps me appreciate the data.

Wow, finally this topic !!! Amazing video, Amir !! Keep making videos !!

[joshua]

I like these much more than your "debunking" vids.

have you ever considered purchasing a vat of liquid nitrogen, submerging a dac or amplifier within it, and then observing the effect on measurements? :)

sounds like a fun / interesting experiment to me even if it isn't practical

[dagnisnierlins]

I found your old YouTube channel, bring those videos here or the topic of high resolution files.

[willbrink]

Another useful vid minus the usual nonsense. Win win.

Thanks for making the videos and explaining everything at an understandable level 😁
