You should be playing back at a 22bit rate to get the sonic benefits of a 16 bit sound. I believe this is the only reason why digital sounds fatiguing.
As far sampling rate, the higher the better,recorders have sharp filters to reduce alaising distortion which can cause sonic problems,the higher the sampling rate the higher or gentler the filters can be.
It is my understanding that bit rate is determined by the media you are playing it on. If you are doing it for film then is the choice. If things were properly made you could use any sample rate or bit depth you want to use and not just what industry dictates you use.
BTW that or 48 or is not really what it says it is. Have you ever listened to firefighters talk over the radio using those throat mikes they sound distorted like they are using a bad sample rate combination.
Let me say i have been recording film and studio from I will make my point short I have spoken to a PH-D. Ask yourself why does Rupert Neve say music needs Voltage? Ask yourself about sd camera you know about bad sound you get inside your sd handy cam? Ok Sony Ask yourself what is a intel Cpu incoder ,Is he or she spoken to RCA Victor, AMS Neve, Rupert Neve ,Solid State Logic and and do they have a have a high iq on mixing console construction have they built-in a stable standalone computer do they offer you a stable 50 year recorder tracking audio computer.?
Why do you give Chinaware a world-class approved audio recorder tracking lie? Ask yourself are you happy with your missing micro capture lie digitization sound? Ask yourself is your computer safe does it make you millions of dollars Ask yourself is major studios closing is major record lables on a shutdown. Working on a 44,1kHz or 44,8kHz is a good option for mixing and music producing. When you record a sample at 44,1, the sine wave at 20kHz will be discretized sampled as a Triangle shape.
For exemple, when people used akai s sampler, the would pitch up their samples in order to stock more in this tiny memory back in the time it was huge! That why when you are planning to manipulate a sound, and especially pitching it down, using 96kHZ material is the best way to avoid those artefact. Wow, that is good stuff right there!
Thank you sir and kudos, keep spreading that good knowledge around the Internet???? Will my DAW automatically resample the loop to And many thanks for inspiring articles and post , i follow you on Insta , Facebook and read you blog. Great question. In the case of Ableton Live, it will automatically resample to project sample rate.
It also pays off to select the high quality conversion in there. So you should always be mindful of what sample rate you are working in and what sample rates you are importing into the project.
I have added a section in the blog post to answer your question, as I think it is something a lot of people are wondering about. I am not talking about recording. Just working with midi or audio samples in a DAW. Great article! How much of a role does your audio interface play in the quality of your sample rate conversion? I a make Melodic Progressive House so I am usually not recording anything except when I record a the output of a MIDI track to an audio track for some specific purpose.
So everything is straight up ITB. I have been debating about what sample rate to use. On my old PC I used 96 kHz. I can hear a difference for sure with the high frequencies compared to So I may try 48 and see how that goes.
But I am curious as to how much the difference the audio interface makes vs the Daw itself. Thank you. Hey John and apologies for late reply. In a normal ITB setup, the audio interface is not doing sample rate conversion. The audio interface then does digital-to-analog DA conversion so that the signal can be sent to your speakers.
There are fairly large differences between interfaces in the quality of this DA conversion. I have not used RME myself but it should be quite good! The Nyquist—Shannon theory explains why we only need a In digital audio the sample rate is the number of samples taken per second of an analog audio signal. Each sample records amplitude values which indirectly gives you frequency information via the sampling rate and by graphing the curve and connecting the samples amplitude values using sinc mathematical functions or something like that break out the graphing calculator.
It also directly gives you volume Dbv information encoded in a 8 bit, 16 bit, or 24 bit word length. This gives you a dynamic range of Dbv values. The more bits the better the dynamic range and the closer together the possible decibel values are.
The actual decibel values will have to be rounded up or down to the nearest value on the scale. An analogy would be if you were using a ruler and measuring everything to the nearest inch. If you sped up or slowed down the sample rate that would affect the frequency. If you play it at the wrong speed the frequencies are wrong but the volume and dynamics are the same. By raising the sample rate you get more Dbv values per second.
It could help in processing dynamics plugins during mixing and mastering. This might be why the industry is going to higher sample rates like KHz. For more accuracy closer to analog in the sound level decibel department. Good article that helped clarify the terms for me.
From all that I have read in my learning, the recommendations have been for Primarily due to the reasons you mentioned about file size. With professional music and audio work, I simply refer to anyone who either works with or aspires to work with audio professionally.
From what I gather, you may be getting two things mixed up here and I should have probably been more clear about it :. For example, you are correct that in most games the end product is at Bouncing the Virus TI into audio online render — realtime that is and listening through Audeze iSine10s. At 48Khz and 16 bit, the stem sounded flat and sterile — lifeless. The 32 bit stem captured it. Then, Reaper offers some 2 or 3 other formats which sound like the 64 bit file.
This will also mean, that it is better to work at high sample rates and bits when you design your sounds and make your sample library. Funny, how I do all these and at the end I batch process all files to convert them to 16bits and transfer them to my S akai sampler. The akai is a crunchy playback of the library.
Mixing and mastering are the 2 processes following. Inside the folder you will throw all the samples you feel like you want to use I use Sononym as well for this process Snapper used to be cool too. Then, you can see what files you have to deal with, their attributes and such. The rest you should know already. Make samples for this project and render them in this folder. I remember when I was 14 and I was making music with HipHop ejay… I could form an arrangement in an evening with no experience at all, just because I had samples and parts ready to be placed on the grid.
This is what you want to do. Drag an drop blocks of audio, your audio. The DAW is there to play back midi and record audio at high sample rates and bit data. Still, is not as easy… My many cents. One detail that has been overlooked is that higher sample rates allow for more high-quality pitch and time processing — at kHz, you could play the material back at 0.
This really comes in handy for sound designers when creating sound effects, and I speak from my own experience as well. My experience is that high bit and sampling rates for end user listening lets in too much noise and dirt that gives me a sickening headache and nausea. My hearing tests to 19, Hz, a cat can hear from 55 hz to 79 Khz way higher than us puny humans.
PS: A big source of noise comes from power cables in your system, under floors and in walls. So keep power cables and all other wires wrapped in a Faraday Cage. Aluminum foil layers or aluminum window screen works great. There is no single right or wrong answer. It depends on what you are looking to do. If you can tell me what your use case is, I can give you my recommendation. Considering that humans perceive up to about 20Khz, when doubled that frequency is What I am saying is: it is better to have more resolution in a given time period than to administer information at a higher rate but lower resolution to the listener….
I am doing research work i have to collect audios and then make segments of single talk double noise etc each should sampled at hz sample size i want to know sample size means file size? This means the Nyquist frequency for CD-quality audio is This sample rate was settled on as it provided the best compromise between audio quality and album length — ensuring a maximum of 74 minutes of music later improved to 80 minutes for some releases.
This means that with a stereo or multichannel waveform like a 5. This messes with the sampling process because we are grabbing bits of audio with frequencies that are too high to be sampled. Oversampling is the process of increasing the sample rate by a factor of two or more, usually temporarily inside a plugin so it can perform a process in higher resolution — most often distortion. Oversampling means more headroom for harmonics that are introduced by distortion and overdrive effects — which can go far beyond 22 kHz.
A good distortion plugin will likely already have some form of oversampling built-in, so even if you are working at Subtle to extreme hardware-modelled saturation.
The secret weapon of top mix engineers. Decapitator brings the best of analog saturation to your digital studio. Bit depth directly relates to the resolution of each individual sample.
Imagine our waveform on a graph where the amplitude of each sample is in the range of -1 to 1. With low bit depths, there are only a limited number of possible values for our samples.
For example, with 2 bit audio, we can have only four different possible values for each sample. Our wave quite literally lacks detail, and can only roughly convey the original sound. For this reason, 2 bit audio is never used, and it sounds absolutely terrible! In fact, anything less than 16 bits is considered low quality.
But in the process of calculating that final waveform, we are processing audio so much that we need extremely precise values for each sample , and 16 bits will not hold up here. For this reason, with digital audio, we use bit depths of 24 bits and above when recording and producing , and 16 bits and above for final renders. The difference between 24 bit and 32 bit float audio is impossible to hear, even in music with a wide dynamic range.
There is no longer any data left to record louder signals. But 32 bit float audio has a much higher ceiling , and if a signal happens to go beyond 0db, it can be safely reduced later on with no clipping.
As you may have gathered, there is a direct relationship between bit depth and dynamic range. A 16 bit audio file can have a maximum dynamic range of 96 dB, which is certainly very acceptable. But it should be noted that very soft sounds recorded in 16 bit quality will have less definition, as they are not using the full range.
All these numbers add up to 65 , so in this case, we are using the full range of values available to represent this waveform. Audio recorded at 24 bits can have up to dB of dynamic range , which is bloody huge! In the early days of 16 bit digital recording, it was important that the full range of values was used to ensure the best quality digital recording. This meant engineers would play a dangerous game as the ideal recording level was only a notch down from the level at which clipping occurred.
With 24 bit audio, this is no longer the case, and digital audio that is recorded softly can be safely amplified without any noticeable noise. This is a term that you may have seen but are otherwise unsure about. So, when we decrease the bit depth, we quite literally lose detail in each sample, and this manifests as mathematical imprecisions.
Some sample values can be accurately decimated without errors. For example, a value of can easily be halved to with no loss in quality. But a value of, say, , cannot be divided as easily. We end up with Dithering counters this noise by — drumroll — applying even more noise! If you are happy to receive these types of emails, please confirm here:. We treat your information with respect.
