what is the relationship between bitrate and sampling frequency and the quality of the sound file?

As the bit rate increases the amount of data streamed per second increases at a good sampling rate to produce the replica of analog signal with more bit depth(16 for audio) thus increasing the bandwidth and file size to produce the best audio quality.

In summary, I thought both physical CD's in MQA sounded better than their streamed counterparts. The SACD physical format was a very close second to the physical MQA and quite possibly equal to, and depending on the system, better than streamed MQA.

M4A files are encoded with the lossy Advanced Audio Coding (AAC) codec, which is able to provide the same bitrates as MP3s, yet achieve tighter compression. This results in smaller file sizes, all while delivering higher audio quality.

Bit rates range from 96 to 320 kilobits per second (Kbps). Using a bit rate of 128 Kbps usually results in a sound quality equivalent to what you'd hear on the radio. Many music sites and blogs urge people to use a bit rate of 160 Kbps or higher if they want the MP3 file to have the same sound quality as a CD.

For files with more channels (e.g. surround sound), you want correspondingly higher bit rates. So basically, you could hear the difference 160 and 320 kbps if there are more than 2 channels, as bitrate per channel will be lower. Bitrate is affected by bit-depth.

File Size and Sound Quality. Its lossy compression techniques produce reduced file sizes without much audible loss of quality. The longer the sound lasts, the larger the file. The greater the sampling depth the larger the file.

In summary, sample rate is the number of audio samples recorded per unit of time and bit depth measures how precisely the samples were encoded. Finally, the bit rate is the amount of bits that are recorded per unit of time.

With Deezer HiFi, you get High Fidelity sound - that means you get uncompressed music files encoded in FLAC format (16-bit, 1,411 Kbps). Essentially, lossless quality is crystal clear, CD-quality audio.

['10 megabits per second: 720p, 60 fps, stereo sound.', '20 megabits per second: 1080p, 60 fps, HDR, 5.1 surround sound.', '35 megabits per second: 4K, 60 fps, HDR, 5.1 surround sound.']

Bit rate is the amount of bits per second that an mp3 outputs, the higher the better. Bit Depth is used to determine the range of measurements.

There should be no difference audibly between a lossless format like FLAC and an uncompressed format like AIFF. Plus you get the benefit of a lower storage requirement, somewhere between 30 and 40% less on avaerage. The difference is the size of the files. Lossless files take up half the space of the originals.

WAV is an uncompressed format, so it has the best audio quality. MP3 and AAC are compressed formats. However, MP3 and AAC files at 320kbps are very hard to pick from WAV files for most people.

This is most likely because the audio levels are set too low in the original edit file. As you probably know, audio is measured in decibels 'DB'. ... Sounds levels much lower than -12 DB will result in quiet audio on most devices, even with the volume cranked to full.

The rate of capture and playback is called the sample rate. The sample size—more accurately, the number of bits used to describe each sample—is called the bit depth or word length. The number of bits transmitted per second is the bit rate. Let's take a look at this as it applies to digital audio.

For audio-for-video work, most producers stick to 48 kHz or 96 kHz for best compatibility. But can you get better sound with higher rates? The best way to decide is to do your own testing. Record tracks at standard (44.1 or 48 kHz) and at higher rates (88.2, 96, 176.4 or 192 kHz).

Now take a look at digital---as in DACS and built in DACs in a CD player too. THEY ALL SOUND THE SAME. They all have the identical curve. The big difference with a DAC is in HOW the digital is implemented.

It depends on the resolution and on the bitrate, also on the codec sometimes. In general a HDrip and a Web-DL are likely HD while a DVDrip is SD as the source if SD. If you have a choice, check for a 1080p or 720p rip of either a HDrip or a Web-DL. Maybe there is also 4k rips, which would be even higher resolution.
