Acoustic Sounds is so much more than its title implies. If you want to bolster your selection of quality radio hits and classic recordings, this site should be on your shortlist. Formerly known as the Classical Shop, and now going by the name Chandos featuring the Classical Shop , this store hosts music from more than labels and boasts a massive collection of classical and jazz tracks numbering over a million. There are also a claimed 80,!

A host of subgenres in the classical and jazz realm are also available in hi-res studio masters. Unfortunately, since Chandos took over, the helpful search tools for sorting by format are now gone. Still, this is a massive database of instrumental mastery with tracks that are totally affordable.

Though not nearly as extensive as The Classical Shop, this year-old French-Canadian site has a great selection, good organization, and even a cool catalog section with pages that turn like a virtual book. The site hosts hundreds of titles, and can easily be navigated by composer, artist, or genre, though we also love perusing the curated album collections.

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.
