Head over to the MQA website here. Listen to the What Hi-Fi? During that time she has been fortunate enough to travel the world to report on the biggest and most exciting brands in hi-fi and consumer tech and has had the jetlag and hangovers to remember them by.
In her spare time, Becky can often be found running, watching horror movies and hunting for gluten-free cake. What Hi-Fi? Becky Roberts. See all comments 7. I believe that many other Tidal users are figuring out this too.
Probably the easiest way is through Tidal's desktop application. Just make sure that your sound output settings are bit and 96kHz. The Tidal mobile apps don't encode MQA-files, so with them you will need an encoder. With Apple airplay, bluetooth or HEOS, you are limited to 44,1 kHz, so if you want to move the sound to your home studio, you will still need to figure out a way to get the sound from the encoder to the AWR.
The DACs I would leave to hifi-enthusiasts. It is more nonsense from Bob Stewart. MQA has been proven to be lossy, adds ringing to the file, not takes it away, Is not higher that 48KHz as the supposed 3rd unfold is just oversampling method, pays Bob Stewart and his ilk a small amount for every part of the chain MQA is used on, sounds better because the file is db louder than a same FLAC version of the file.
MQA also adds a watermark, which hasn't been turned on yet, but as soon as it is one will have to pay more to play the files.
The following notes and descriptions are from David himself:. Listen to these samples of "Vision of Her" on the OPPO and try to form your own opinion of what sounds "right" or "best" to you. That is how the song was recorded and mixed and mastered. This transformation process used a software application from Korg called AudioGate. In these cases, AudioGate was used to "downsample" and convert the original DSD source audio file to the various PCM formats at varying lower resolutions.
As a general rule of thumb, the lower the PCM sample rate, the lower the sound quality on playback. This is Important to Think About: If you create a very high resolution recording and turn it into lower lossless or lossy formats, it can still sound very good because the source was good! You cannot do the reverse which is take a very poor sounding recording in any low resolution format and make it sound really good in a higher resolution format.
This is why I always encourage musicians and studios to use DSD for their source recordings! If you are unsure about what audio hi-res is about, think of how high resolution photographs are presented.
If you take a 12 megapixel digital photo as a clear image, it can have terrific quality. It can also be reduced to a very small JPG say pixels at 72 dpi and still look quite good. However if you start with a x pixel graphic image and try to expand that to say x pixels, you will not see any improved quality in the result. In fact, it will probably look a lot worse! DSD gives you that very high quality source image which translates very well to other formats including PCM and vinyl.
The acoustic trio was arranged in a small circle with minimal micing and no isolation. The live studio takes captured and presented with no effects, edits or overdubs. Multichannel 5. The 5. This track demonstrates the power of a live acoustic band with overdubs added for the electric instruments guitar and pedal steel. Our site is affiliated with Audiophile Inventory only.

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. Identity of two interfaces is more sophisticated task, than the splitting. When a single sample music album is converted to test with software , we don't know that we compare: converters or resolution. But, even, when converted samples are played back at single DAC, it may works in different modes electrical circuit, digital processing for various resolutions.
High-resolution formats contain ultrasound. Theoretically, it is does not matter for ears, because we don't hear it.
But, practically, musical hardware and, sometimes, software have non-linear distortions. It can cause audible products from inaudible high-frequency components intermodulation distortions. In general case, higher sample rates and bit depth guarantee nothing. Result depends on implementation quality.
A professional audio interface at Hz can give better sound, than a built-in sound card at kHz. If consider altering of resolution resampling as itself, it lossy processing always.
And the system may have different distortions for various modes combinations of sample rates and bit depths. So, we can optimize the recording to better playback mode: choose the mode with minimal distortions. To reduce conversion losses, audio conversion algorithm should have minimal distortions. However, it needs to remember, that sampling rate increasing don't give advantages at its own. Theoretically, in some cases, reducing a sample rate may make sound better. In other cases, no audible difference between resolution.
Each case should be learned individually. But these formats are intended for music production and scientific purposes rather. Only part of the DXD spectrum contains useful musical signal. Noise level is growing with grow of frequency. However, there are PCM lossless formats may be used too. Traditional PCM has no significant noise level grow at high frequencies. More about DXD here. As rule, it has compression ratio better, that FLAC. But, as the author know, MQA is not lossless no losses of information after restoring of sound from compressed stuff.
Read details here. Also read about MQA. Read more what is the best hi-res music format? All these formats give musical system designers the same abilities. Final result depends on how music system is done. PCM has no technological noise "hump" at high frequencies. However, we don't hear ultrasound see details below in "Myths". And the noise is not audible.
