wow, just wow...the amount of thought that went into this. You take us through each concept so perfectly step by step. I honestly don't know if anybody could have explained this so well. Your teaching skills are through the roof. I just want you to get that this kind of teaching skill is just not normal. I just subscribed...because seriously...seriously!
@Fusionicon: I'm not sure what equations you're referring to. If you're talking about a particular statement made during the video, let me know at what time so I can review it.
I have a tutorial in the works about dithering. Not so sure if I'll do a fixed/floating point tutorial, since I'm trying to keep this channel music/audio related. If you could think of why this would be important in an audio context, I'll definitely consider it :).
This is my first "non-player" video - I hope you enjoy it. Criticism is welcome. By the way, despite encoding the video using MPEG-4 @ 640x480, RU-vid still degrades the quality considerably. Any experts on the subject with advice on improving this are welcome to make suggestions!
This was an excellent “conceptual” explanation of these otherwise very abstract recording sound ideas. I am definitely subscribing to your channel. I am a neophyte beginner when it comes to home studio music recording and the ‘pace’ of your explanations was perfect for me. Thank you so very much and you’re an exceptional instructor 👨🏫.
Excellent video ! You not just explained what's sampling and bit depth but also proved it. The way you should how both signals match each other after adding more bit and frequency, it was so amazing !
Thank you so much! I've always been a visual person and your visual representations and examples made it a lot easier for me to understand. Very well explained
I've never heard any significant difference between the 16 and 24 bits, although some people claim they do. My classical music CDs, which usually display the widest dynamic range, sound fantastic and "uncompressed" to me. From a physics perspective, 16 bits give you a much wider dynamic range than what you'd encounter in everyday life. Anyway, with today's uber-compressed music, I suspect 8-bits will soon suffice :).
With a noise shaping 16 bits can give about a same dynamic range as 24 bits can. The only reason of 24 bits is to make a better result with a further DSP. For an output 16 bits are more than enough.
Subscribed for the clear cut animations. After watching so many videos about digital audio, I only got the idea of sample rate. The bit depth was an enigma until I watch this video. Thanks a lot.
Thank you. Glad I could help out. There's also a related dithering tutorial I've put up a short while ago (I haven't gotten around to making in-video links). You can find it at /watch?v=U2mwXiJqAgA.
This is a fantastic tutorial. It's so nice to see a video like this with no trash talking in the comments and zero dislikes. Thanks for uploading. You earn one Karma Credit. :)
Asaf.. im not sure if your aware of just how a good a teacher you are ! Even though you oviously have alot of knoledge about the subjects in your videos, you are still able to 'humble' the information and completely relate to the mindset of a beginner in the most perfectly straightforward and simple manner. Even for someone like myself who has some knoledge, this is an excellent way to re-cap on things. I can only wish you much success in your career as gratitude for these videos.
excellent explanation. finally someone who didn't just say "the higher the bitrate the better the quality" and went silent expecting the audience to take that as the best possible answer.
Thanks Alis. I think there are some of us out there who still rationalize our choices :). In the end however it's important to realize our ears are the real judges. I didn't know anything about bitrates or sample rates twenty years ago when I started playing, but I could immediately tell what sounded good and what didn't. Some people today create 8-bit music and it sounds awesome, although rationally speaking an engineer would say you "shouldn't" use 8-bits when you can use 16 or 32.
MangoldProject You are welcome. I understand now why 44KHz sample rate is standard in music production. But can you explain why is 48KHz and not 44KHz an audio standard in video production?
I never understood all this bit and sampling stuff and got so frustrated when setting up my recording kit to my lap top. Now I fully understand what it all means and it all makes sense now thanks to you. I think the biggest point I never grasped was that the computer had to break a sound wave down into NUMBERS . It never dawned on me although I know computers run with ones and noughts.
The way you explained is the best ! Very simple to understand. I can see that you worked hard to make this video. I really thought you used animation software. This is also a great skill to get what you want by just using a simple software.
This is a really good tutorial. I understand everything mentioned very clearly. This also explains why my sound always loses quality when I record my voice. >.>
@MangoldProject As for why quantization is needed: it's a necessity. Ideally, we'd like to do away with it, but your computer has finite memory and processing capabilities, so it must store the voltage of the recorded waveform using a finite set of numbers. It's part of the price you pay for going digital (analog waveforms also have "effective" resolutions because of signal to noise, etc., but that's a different story.)
