The M15 adopts a fully balanced architecture to ensure every last detail can be heard without sacrificing bold dynamics. The PCM can also be configured to output either 64x or x oversampled, 1-bit direct stream digital DSD data for each channel. Distortion dB Optical Input Toslink. That’s why it would make sense if wanting to use PCM rather than DSD, to use an external higher quality “oversampling filter” which is the same thing as the interpolation filter.
These filters attenuate that high-frequency noise. And it works. Adding criteria. Special device – analog-to-digital converter – rapidly measure momentary values of the audio signal its voltage. Let’s imagine a machine, that can form water level by the written value sequence. And we get the same water wave. Analog-digital converter ADC is a device, that periodically measure analog signal voltage and send the measured values as numbers in digital form to PCM digital audio output.
PCM encoding is the conversion of an analog signal to digital form. Quantization is the measurement step of the voltage level of an analog signal. Samples may be stored and transmitted without altering of information. It is the main advantage of digital signals, comparing analog ones. Sample rate sampling rate is a number of samples per second measured in Hz, Hertz. As rule, an analog signal is coded as real numbers math definition , that are usual numbers we use permanently.
Let’s pay attention to “theoretical” word. Real implementations require to account other factors too. Read below about myths, where we’ll discuss, why higher sample rates are used. In simple words it is not exact math definition the Nyquist—Shannon sampling theorem may sound as:. Below we will consider the theorem details, when More exact the theorem wording in sound terms: Endless analog sine signal may be coded to digital form and restored with sampling rate 2 times more the signal ‘s frequency.
M ore samples per finite signal duration keep more information about source signal to restore it from digital to analog form. More samples per duration, it is closer to infinity. Alternatively, the input samples may be processed via Hilbert transform. It converts real numbers to complex ones. Analog-digital converter capture full frequency band at the input. It adds noise to the coded digital signal. But the analog filter isn’t steep enough. Also in DAC sampling rate may be increased oversampling to better work with the analog filter.
Oversampling works with the digital filter in pair. There is a myth that non-multiple resampling causes more distortions, than multiple one. But in case and Hz, resampling is applied the same way. Maximum value of the word is the maximal positive value of an analog signal at ADC input. Its code is:. Minimal value of the word is maximal negative value of the analog signal at ADC input. Rounding is bit depth reducing via removing of one or more bits with altering of reduced number according to removed bit s.
Codes of analog values, stored into the words have precision limitation. The limitation is defined by total number of measured levels L.
So stored codes samples are not equal exactly to real analog voltage. Quantization error is difference between sample digital value and real voltage of analog signal. The energy of quantization noise is constant in total band. Thus, increasing of the total band of an analog signal after DAC sampling rate increasing decrease the noise level in the audible range [ It happens because audible range has a fixed width.
In the digital domain quantization noise level is decreased about 6 dB for Fourier transform length 2 times more. In the digital domain, N Q is the same independently sample rate. But the Fourier transform divide digital band to parts small sub-bands. Fourier transform is converting oscillogram time domain to spectrum frequency domain.
In digital audio, we mean discrete Fourier transform in most cases. The discrete mean, that spectrum is divided to taps. FFT fast Fourier transform is case of Fourier transform. It’s length is 2 K , where K is integer number.
If there are tips 2 times more, noise energy is redistributed. And each tap have energy 2 times lesser. If we make tap width as before the redistributing tap width at the part A of the picture , noise level will 2 times lesser. Because square of noise is constant. It happens on computer display, when tap width have same pixel width on a screen. Read below more about bit depth, quantization noise and dynamic range for 16 bit implementations. But it is not so. Because “the stairs” are smoothed by analog filter at the digital-analog converter output.
But that’s not exactly true. Because the analog filter isn’t ideally “brick wall”. Half of the aliases are flipped horizontally. In ideal audio system without non-linear distortions these aliases will inaudible. In the table noted only file abilities, that author know. If you have additional information to correct description or other, contact us. Sometimes files with same extension may contains different extensions. A reading software player, converter, editor, other parse file.
As rule, file consists of data blocks. These blocks have identifiers. And the reading software recognize the block types. Sometimes the software check data integrity. If there are non-correct data, the software may to reject file opening depend on implementation.
Size compressed file types are used for saving hard disk space. Especially, it is actually for portable devices: digital audio players DAP , mobile phones, etc. Portable devices are able to playback multichannel files. But it is listened at stereo headphones, as rule. So multichannel records consume disk space to extra channels.
The space extra size issue may be solving via downmixing audio files to stereo. It is impossibly to get rid of jitter in real music systems. Because there are electromagnetic interference, non-stability of clock generators, power line interference issues.
Quantization error cause non-linear distortions. It correlate with musical signal. Correlated distortions are considered as especially unwanted to perceived sound quality. Dither is extremely low level noise, that added to musical signal before ADC or before bit depth truncation prior to DAC. To reduce noise in audible band, noise shaping may be applied. It looks like “pushing” of noise energy to upper part of frequency range. But the shaping demands of band reserve to the “pushing”.
Size compression of audio content is way to save space at hard disk or increase throughput in communication line. Compression is performed by encoder and decoder software. Lossless compression is size compression when input and output binary audio data content are identical. Lossless formats have same sound quality. There is opinion, that different sound may be there. Some objective hypotheses exists too. But still no researches, that are famous to author.
Lossless compression is size compression when input and output binary audio data content aren’t identical. Different lossy formats look for minimal losses by psychoacoustic criteria.
And these compression methods are based on various hypotheses. As example, AAC format was developed to improve mp3 sound quality according newer knowledges about brain processing of sonic information [ 1 ]. From this point of view, mp3 and FLAC are “bitstream” too.
As rule, higher stream volume for single codec give better sound quality. But, other hand, higher bitrate may lead to lesser channel number in fixed band width of digital interface.
As example, stereo instead multichannel. AV users asks what is use PCM or bitstream to transmit data from player to audio-video receiver of home theater.
Otherwise, use bitstream codecs. Dolby is size compressed PCM. It used to transmit audio signal thru digital audio interfaces with lower speed. If compression is lossless, it is not matter Dolby or original PCM there. Lossy compressing cause some quality losses. Generally, it is impossible to say, the losses will audible or not.
Because different hardware is used there. It is common PCM in audio. Sound quality mean distortion level. However, distortions may have different distribution by frequency and phase. And distortions must be estimated in the light of psychoacoustics. Aliases distortion appear during analog-to-digital and digital-to-analog conversion. Sample rate define the alias period on frequency axis. The period is half of sampling rate. All audio content above the period should be removed to avoid of distortions of useful musical signal.
The analog filter makes the removing. However, analog filter isn’t steep. Bit depth define minimal noise level into record. If recorded musical stuff will digitally processed gain increasing, equalization, level normalizing, other , noise floor of processed stuff should be below DAC noise level.
In audio software, processing may be implemented in or bit float point formats. These formats have high precision low quantization noise and better overload abilities, than integer ones.
As far as author know, DAC can’t receive data in float point formats. These formats are rounded to integer into playback software to send to DAC. DAC with sigma delta modulator are able to receive float point formats.
But author know nothing about such real implementations. It give base to myth that Hz is maximally reasonable sample rate. And there is opinion, that higher sampling rates aimed for ultrasound playback, that we can’t hear. Nyquist theorem, indeed, says that analog sine may be coded to digital PCM and restored back to analog without loses. But it is ideal concept, that require infinite time of recording and playback and ideal brickwall filter. Narrow transient band is difficult for analog filter.
Steeper digital filter, more intensive its ringing distortions. Also may be technical resource limitations to build steep enough filter. Inside DAC upsampling with digital filter is used for proper filter work. But hardware may have calculation resource limitation to implement sophisticated filter. We know that human hear sonic in range To keep sound quality signal must be higher noise.
We can take noise level about dB as allowable. Digital audio data may be corrupted in transmitting or at storage. It can be checked via checksum comparison. Audiophile players are capable to bit-perfect playback of audio files: audio file content is sent to DAC without altering.
CD ripper is kind of audio converter that capable to copy CD audio data to file. PCM mode provides sound quality without quality losses. This codec transmit sound data without losses of sound quality.

Audiophile players are capable to bit-perfect playback of audio files: audio file content is sent to DAC without altering. CD ripper is kind of audio converter that capable to copy CD audio data to file. PCM mode provides sound quality without quality losses. This codec transmit sound data without losses of sound quality. We can convert analog audio to digital one various ways. PCM one of the ways. Most recommended output type is HDMI due to better abilities for multichannel hi-res sound streaming.
It provides the best sound quality. So, compressed audio format may be required. Especially for mulichannel signals. It provides lossless sound quality. Some of PCM formats support high quality audio. Dolby Digital is family of size-compressed PCM audio formats. Dolby Digital formats may be lossless by sound quality or lossy compressed.
Lossless-format family is the best. To achieve the best sound quality, use one of lossless audio formats. To save hard disk space “seriously”, use lossy-compressed audio formats. These formats also provides high sound quality. Lossless formats save full sound quality of original recording.
Dolby Digital if family of size-compression methods of PCM pulse-code modulation audio with or without losses. Dolby Digital is one of PCM format family. Losslessly compressed formats causes lesser distortions than lossy ones. Dolby Digital supports both types of the compression. Dolby Digital is lossy formaty in many cases. So, using uncompressed PCM is preferable, where no requitiments to:.
HDMI is just protocol and hardware interface to transmit audio data. PCM format is digital representation of recorded analog sound.
These factors should be considered in complex according to your application. However, the best-sounding audio resolution is matter of used musical equipment rather. PCM is audio format family. Sometimes, size-compressed PCM audio is called as “bitstream audio”. Bitstream bit per second is used to easier estimation of efficiency of size compression or communication channel abilities.
But higher sample rates of compressed audio may give advantages in sound quality. PCM mode is recommended for surround and other sound. PCM audio may be compressed or not. PCM audio output is hardware interface connector and its controller. The interface is capable to transmit digital audio data in PCM format.
RAW is pure audio data without meta-information about the data. The information contains: sample rate, bit depth, channel number and others. The audio data is splitted to portions frames. Each frame group of frames have a header. As rule, the meta-information contains in the header. PCM audio one of audio formats. In TV applications it’s considered as a lossless one. So, PCM provides maximum sound quality. Therefore, compression, lossy and lossless, may be required.
AAC is newer than mp3. And AAC developers promise better sound quality. Also, AAC supports high resolution audio. DTS is one of formats of Dolby Digital family. It allow to support either lossy or lossless compression. Dolby TrueHD support higher audio resolution and channel number.
See details in the table Sound form an audio unit to a speaker , may be sent in different PCM formats, that provide compatible phase and amplitude response.
