Does hi-res audio really sound better than CD? There is no simple anwer to the question. Keep reading to know details. At the picture we can see approximate artistic visualisation of sound format difference. It is not real differing. Implementation of the musical systems is matter.
But we can see general trends. High resolution has not these "analog" issues and may have lesser aliases shifted copyes of original signal comparing Read explanation below.
Hi-res audio was designed to provide higher sound quality and better listener experience, than standard CD-audio. Read below: is the aim achieved or not? PCM Some kinds of music with a wide range of instrument loudness like classical, jazz , demands a wider dynamic range of a musical system. The range may be achieved via increasing of resolution. It is audio, that provides minimum distortions.
Higher sampling rates and bit depths give potential abilities to achieve better sound quality. But, actual result depend on audio equipment and software implementation.
It is necessary to remember, that an actual DAC noise floor is limited by electronical noise approximatelly dB. However, with 32 bit formats, engineers almost not to have to worry about digital processing into a digital-to-analog converter. Other hand, there are other factors, that can increase or reduce audio quality. However, lossy audio formats AAC, mp3, etc. We havn't full control of recorded level.
As example, in classical music recordings. Digital recording demands some tricks to avoid analog and analog-to-digital conversion overload distortions, that can not be fixed after record. However, reducing of analog signal level at analog-to-digital converter ADC input can cause worse signal-to-noise ratio.
Especially, for low-level fragments of a musical piece. In general, noise level of digital representation of an analog signal quantization noise , should be lower, than ADC's own electrical noise relative overload level. We record a symphony orchestra in 2 microphones. To avoid overload, we reduce input analog level of ADC. It give some loudness reserve.
But it degrade signal-to-noise ratio of quiet musical fragments. More reserve is more the degradation. If we use lower bit depth resolution, it can cause quantization noise, that is higher than [electrical] noise floor of the DAC.
And the signal-to-noise ratio get more degradarion. However, resolution of further digital signal processing DSP , may be increased, to "transparent" for DSP designers work with sound. Read more and details in " Does 24 bit sound better than 16 bit? There are many questions about the necessity of hi-resolution musical recordings. One people thinks, that "excessive" resolution waste disk space only.
Other people think, that such records are needed to produce ultrasound. But, by author opinion, existing of high-res may be useful and have other reasons. Read " Myths " part below. High-resolution audio file formats sample rates. High-resolution music file formats bit depths. Opinion, that high res gives advantages always, is not correct for all cases.
Sometimes people, who play records with high sample rates, stumble with unexpected noise or other unwanted sounds. In " Myths " part you can watch the video with example. Separate [DAC-headphone amplifier] device may be used to connect to a mobile phone, portable player, computer and etc. High resolution audio solves issues of non-linear distortions primarily. However, it is one dimension of the sound naturalness. Second dimension is spatital distribution of acoustic waves in the listening point.
Read details It's only one of many factors. But it give potential technical abilities to improve sound quality. When bit depth is discussed, human hearing range about dB from inaudible to pain is taken as the reference value. It looks like enough to cover almost full range dB. As an example, we want to provide proper sound quality like tape's 60 dB at 0 dB audible level. So we can add about 60 dB to dB total about dB to provide allowable quality at lowest levels. Why depth, higher than 16 bit, is need.
It is not exact numbers, because the author doesn't have a result of researches. But we can get it as the hypothesis. Direct Stream Digital solve the dynamic range issue via noise shaping. And we begins to listen these places better way. But noise is boosted together with music.
And it degrade sound. To reduce noise of quiet places of the piece, we should reduce noise level there. If bit depth is bottle-neck, we can do nothing. However, the reserve is considered abstractly. Real-life filters are analog. And have wide transient band. To solve the a wide transient band issue, digital filters and higher sample rates or oversampling are used. To reduce necessity in "hard" efforts to proper filter transient band, higher sample rates including DSD may be applied.
High res is not intended to recording and playback of ultrasound. Analog filters are not steep and can't suppress aliases properly in allowable band 20 Higher sample rates allow placing aliases at higher frequencies, in better suppression range of the analog filter. However, an issue with the quality of filtering may be there due to limited computing resources of hardware. And ultrasound playback is sequence of higher sample rates.
Ultrasound playback is not target of hi-res records. Practical experience, that may be checked right at home, says, that we can't hear sines with frequencies above And there no surprises for number trials. This study doesn't found a significant difference between samples with and without very high-frequency components. However, the authors of the research neither confirm nor deny a general human possibility to discrimination of music with and without the components.
Some of the studies show, that we may have a brain response to ultrasound. But, it is unknown, how ultrasound impact to sound quality. Digital signal doesn't cause "stairs" in any resolution. Because analog filter at output works as interpolator connect momentary voltage values of digital samples via smooth curve. For high resolutions, interpolator analog low-frequency filter is easier to implement in better quality see myth 1.
As rule, such comparison considered as a blind test of samples provided by a label in different resolution. As an example, we split signal from microphone to 2 audio interfaces, that works in different resolutions.
But we can't split absolutely identically. It is used for storing audio files and sound data in general. Apple created this particular type of file, and it is easily opened and reproduced on any iOS device.
If you use the AIFF file format on non-Apple devices or media players that are not compatible with it, there will be some converting included.
At least if you want to reproduce them. The same goes for adding music to amateur video editors. If you want to add any type of music to your videos using free editors sometimes in premium versions as well , you'll probably have to convert AIFF or even WAV files to MP3. Everything is set, except the music that will make driving easier. We had a vision and did our best to fulfill it. We think that we did a good job, how about you? Also, the kind words of our users give us a lot of extra fuel to work on improving our services.
