Can someone please explain to me the differences between 24bit/96 kHZ and 24bit/ kHz recording sistems (sample rates). I'm using M-audio Fast track pro but I'm going to replace it with Presonus Firepod. Well the FP is not a 24 bit/ kHz recording interface, but I still want to know the differences for my future purchasements. Thank you! And a bit 96KHz recording has 1,,, potential sampling points each second (96, x 1,,). This means bit 96KHz recordings have roughly 33 times the resolution of a bit KHz recording and a bit KHz recording has roughly time the resolution of a bit KHz recording. No small difference. High Resolution (24bit - 32bit/ 96kHz - kHz) Narration Production. Sound resolution is determined by the sampling frequency (kHz) and the number of quantization bits (bit). The higher resolution of the digital sound, the closer it is to the original.

Interestingly enough, not everyone agrees that greater bit depth and higher sampling rates are good things. This blog will explain the math and physics of digital recording and musical reproduction in layman's terms so that you can decide for yourself if this is progress or simply marketing madness.
If you're not sure if you should believe the statements in this blog that contradict much of the marketing hype, myth, and legend in the audiophile industry, feel free to check the references at the end of this blog that were written by recording engineers, such as Dan Lavryand companies that manufacture electronics used in recording studios, such as Antelope Audio.
PCM: Myth vs. There are 8 bits to a byte, and a byte is known as a digital word. This is why everything in the digital world is divisible by 8. Historical note: The bit format existed long before bit digital-to-analog converters DAC were commercially available.
The same is true of the bit format. The horizontal X axis represents time or sampling frequency and the vertical Y axis represents amplitude or bit-depth. In the graphic below the white wave form represents the musical signal being quantized and the green step pattern overlaid on the white wave form represents the quantized values. Sampling rate is the frequency at which the amplitude of the analog sound wave is sampled.
The The 96KHz sampling frequency used in the 7. Bit depth translates to the number of steps the amplitude of the analog sound wave is divided into at each sampling. A bit recording has 65, 192khz 24 bit recording file download, steps, a bit recording has 1, steps, and a bit recording has 16, steps.
Yes, you read that correctly: a bit recording has times the number of potential amplitude steps as a bit recording. Doesn't that 192khz 24 bit recording file download like a rather excessive amount?
So a bit And a bit 96KHz recording has 1,, potential sampling points each second 96, x 1, This means bit 96KHz recordings have roughly 33 times the resolution of a bit No small difference. So why is it that HD recordings sound only slightly better than a bit Dynamic range is the difference in volume between the quietest and the loudest passage, commonly measured in decibels dB. And actually listening to the dynamic range of a bit recording dB would cause permanent hearing loss, 192khz 24 bit recording file download.
So why on Earth would they even create a digital music recording format that can't even be listened to?!?!?!?!? Later in this blog I'll explain how using insanely high bit-depth and sampling rates far above the range of human hearing is used during the editing, mixing, and mastering process to lower noise in the significantly lower resolution commercially released recordings we listen to.
Sorry to burst anyone's bubble and contradict marketing hype, myth, and legend in the audiophile industry, but just because a DAC is capable of decoding bits doesn't mean it is capable of actually resolving that bit-depth in the output stage. And don't even get me started on DACs with tube output stages: the lowest noise floor on a tube output stage is about 90dB which means despite whatever the manufacturers may claim they can't even resolve a bit recording.
Dynamic range expresses the loudest possible sound, and noise floor expresses the quietest. If you want to hear the LSB on a recording, 192khz 24 bit recording file download, the volume or voltage of that bit has to be above the noise floor of both the room and the equipment in your system.
We already know that a quiet room has a background noise level of about 30db that we need to rise above. Even after the equipment is playing above the 30db room noise, the power supply of the electronics will mask the LSB if the peak-to-peak voltage of the noise in the power supply is not less than the voltage of the LSB. Based on a 2. According to the experts that manufacture the finest DAC chips, 192khz 24 bit recording file download, resistors, and power regulators, there is theoretically no way to make electronics that are capable of discerning greater than a bit resolution dB dynamic range.
Any company that claims greater than bit resolution from their DAC is simply full of shit. Oh they can decode bits, because bits does exist in software, but the output from their DAC has less than bits of resolution and dynamic range.
According to mathematical theory, sampling at more than twice the maximum audible frequency only plots more points along the same curves when the digital signal is converted back into an analog waveform.
So in order to correctly sample a 20KHz note, the maximum frequency human ears can hear, you would need to sample at greater than 40KHz. So why would there be any need for higher sampling frequencies than One reason is quantization noise. Since quantization noise is present around the sampling frequency of a PCM recording, a This quantization noise needs to be filtered out, so all DACs have a low-pass filter at the output.
Because the quantization noise is only one octave above audibility the filters used have to have a very steep slope so as to not filter out the desirable high frequencies. These steeply sloped low-pass digital 192khz 24 bit recording file download are commonly known as "brick wall" filters. Though you hear a lot about "brick wall" filters in the top end of early Red Book CD players causing an audible distortion, the fact is that was only a small part of the reason early Red Book CDs had an unnatural sounding top end.
Most of the hard, harsh, unnatural sounding high frequencies in early digital recordings had more to do with flaws in the power supplies and flaws in the recording process, not "brick wall" filters.
Sorry to be the one to burst your bubble, but despite what many audiophiles may believe, less than one person in a thousand can hear anything above 20KHz as a child, and there is almost no one over the age of 40 that can hear much above 15KHz. Of course if a higher sampling frequency and greater bit 192khz 24 bit recording file download are used for the recording, mixing and mastering, there is much lower quantization noise when the recording is output to the significantly lower resolution commercial formats we listen to.
This is why professional formats, such as bit One of the reasons bit DAC chips were developed was so that the recording engineers could monitor their their editing, 192khz 24 bit recording file download, and mastering in real-time without having to down-sample. There is in fact no rational need to use bits of dynamic range in commercially marketed recordings, and no company has ever released a commercial recording with anything even close to bits of dynamic range dB.
Even though many recordings are advertised as being bit, all 24 bits of dynamic range were only 192khz 24 bit recording file download in the recording studio to reduce quantization noise.
The consumer version of most so-called bit recordings are mastered with the dynamic range of or less than a bit recording So what do they do with commercially marketed so-called bit recordings? They could have released a recording of identical performance in bits, but naive consumers insist on bits, so the record companies trick them by centering bits of dynamic range in a bit frame.
How silly. DSD is no different. Any type of digital recording produces quantization noise that requires a low-pass filter at the output of the converter, 192khz 24 bit recording file download.
To get around this problem single-bit native DSD DACs have noise-shaping algorithms and upsample to ridiculously high frequencies to move the quantization noise far outside of the human hearing limit to allow quantization noise to be filtered out with a minimum of distortion in the audible range. Another consideration of higher sampling rates and greater bit depth is system resources.
Both require more storage space, more RAM, and faster processors. Though the optimal sampling frequency and bit-depth that are required to reproduce accurate music are a matter of heated debate, there is no doubt that excessive resolution unnecessarily uses up system resources and unnecessarily increases the size and cost of components. There are very few systems, even among the best-of-the-best, that can accurately play back the full dB dynamic range of a bit recording. This is why few recordings are even released at the 96dB dynamic range of a bit recording, let alone the dB dynamic range of a bit recording.
Keep in mind that the maximum dynamic range of LP records is only about 60dB. Even Dolby analog master tapes had a maximum of about 90dB dynamic range. This makes it easier to discern low-level details from the louder passages. 192khz 24 bit recording file download compression is part of what gives recorded music the illusion of having more detail and focus than live music.
There was wisdom to the LP record and the analog tape standards. The relationship between amplifier wattage and decibels dB of volume is logarithmic not linear. Manufacturers knew that for every 3dB consumers raised their volume, they would have to double the wattage of their amplifier and double the output of the speakers.
So keeping the dynamic range of home audio under 60dB is much of what allowed home entertainment equipment to be affordable, of modest size, and relatively high-fidelity. Fact is that most commercially distributed HD recordings have a dynamic range that is intentionally less than half the dB dynamic range of a bit recording and significantly less than the 192khz 24 bit recording file download dynamic range of even a bit recording.
Think about it: a 60dB dynamic range on top of a 30dB background noise equals 90db. How much louder than 90dB do you want 192khz 24 bit recording file download listen to music in your home?
More importantly, for every additional 3dB you increase dynamic range, 192khz 24 bit recording file download, you would need to double the wattage of your amplifier and double the output of your speakers. All things being equal, to go from 90dB output up to 99dB, you would need an amplifier with 8 times the wattage and speakers with 8 times the output.
To accurately reproduce a recording at dB, you would need an amplifier with 1, times the wattage and speakers with 1, times the output than it would take to reproduce the same recording at 90dB. Both 16 bits and 24 bits became a standard because each represented the next digital word. Bit depth translates to the number of steps in the amplitude of a digital recording. At a At a 96KHz sampling frequency the amplitude is sampled 96, times each second. At a KHz sampling frequency the amplitude is sampledtimes each second.
In order to reproduce anywhere near the dynamic range these high-res formats offer, you would need amplification with several times the wattage and a fraction of the noise floor of what is currently available to the high-end audiophile.
In order to hear the difference in dynamic range between a bit and a bit recording in a normal quiet listening room, you would have to play the music so loud it would cause permanent hearing loss. When 192khz 24 bit recording file download claim to hear differences between bit, bit, and bit recordings, it is not the difference between the bit depths that they are hearing, but rather the difference in the quality of the digital mastering.
The fact is that even most so-called bit recordings are mastered with less than the 96dB dynamic range of a bit recording and wisely so. So what do they do with commercially marketed so-called bit recordings? When music is sanely dynamically compressed, it allows you to listen at a reasonable volume and still hear all the subtle harmonic cues that reveal the tone, timbre, and room acoustics in the recording.
Of course most recordings are engineered to sound best on a car stereo or portable device as opposed to on a high-end audiophile system. The quality of the recording plays a far more significant role than the format or resolution it is distributed in.
But to increase profits, many modern recording studio executives insist that errors be edited out in post-production, significantly compromising the quality of the original master tapes. So no matter what format these recordings are released in, the music will always sound mediocre, since you can never have higher performance than what is on the original masters. In contrast, some of my favorite digital recordings were digitally mastered from s analog recordings.
Many of these recordings were done as a group of musicians playing in a room with one take per track and a minimum of post-production editing. Though these recordings have a much higher background noise being limited by old-school pre-Dolby 60dB dynamic range master tapes, they retain an organic character that can't be duplicated any other way.
When you hear the organic character and coherent in-the-room harmonics, it is clear why so many audiophiles prize these recordings. The simpler the signal path and the lower the power supply noise, the better the digital-to-analog conversion.
The Mystique is in a class by itself. Explosive micro-dynamics combined with harmonically coherent micro-details reveal the true time, tune, tone, and timbre of the original performance, 192khz 24 bit recording file download.
