How to record wav file in bit depths lower than 8 bit?

Lower bit depths are not easily available simply because they are not looked for commercially, not because of some intrinsic technical difficulty. Audio interfaces or other capturing devices have ...

Converting from float 32 PCM to signed 16 PCM. Does it matter if I resample before or after the bit depth conversion?

I think the way you currently have the pipeline set-up is the right way to do it. Conversion should be the last block in the chain for sure as this will ensure that any processing artifacts are ...

how to list bit depth and bit rate of all. files in a set of nested folders?

SoX (Sound Exchange), the self-described Swiss Army knife of sound processing programs is super-useful for these kind tasks. soxi is the specific tool to list audio file information and on Linux (or ...

Bit depth calculation doesn't seem to add up

It's an MP3 file. You can't deduce anything from that other than the fact that it's probably got a bit depth of 16 bits. Try the same exercise but using a WAV file. You will have better luck. MP3 is a ...

What frequency/bit depth were the Beatles recorded at?

The article you read has either been misinterpreted or was monstrously misleading. It is possible that what they were referring to was the fact that the frequency response required from an analogue ...

Is it worth it to use 32-bit (float) in Audacity while mixing down to 16-bit?

The advantage of working at a much higher bit- or sample-rate internally than either your initial input or final output becomes more & more apparent as you start to rack up more channels, group ...

Is it worth it to use 32-bit (float) in Audacity while mixing down to 16-bit?

If the file remains at 16bits, each step of your mixing could add a unit of amplitude and a noise (around -96dBFS) will accumuate. Then it is better to work in higher resolution. At 24bits (fixed) or ...

Converting 8 bit sound into 2 bit sound

Taking the 2 MSBs should be just what you're after. The way I think of it is that 1 bit (1 or 0) simply tells it the signal is above or below the middle value - and since we're talking audio, that ...

What is Tidal's 'Master' Quality sample rate and bit depth?

Fi: 44.1khz/16bit (1411kbps) Master: 96khz/24bit (4608kbps) Pitchfork Article Note that only ~30,000 tracks are MASTER quality right now You can tell that Master is available by the M symbol and ...

MP3 and bitrate

Your assumption that bitrate = bitdepth * channels * samplerate is true for raw PCM encoded audio. It is not true for bitrate reduction encodings, be it lossless (as flac) or lossy (as mp3). The ...

How can I detect the sample and bit rate coming from my iPhone?

TL;DR: It appears the iPhone 6 supports 24-bit audio and 48 kHz playback. So I found a way to empirically test playback. This first screenshot shows a recording of playback over iPhone USB into ...

How can I detect the sample and bit rate coming from my iPhone?

Unlike some earlier models of iOS devices, the DACs and ADCs in the iPhone 6s and 7 support native sample rates of 48000. You can experimentally test for this by writing an iOS app that configures ...

Is DSD actually practical or just theoretical

Partial answer : Many Analog to Digital converters are actually implemented using a one bit ADC at a high sampling frequency (several MHz). The bitstream is then decimated to more common formats like ...

Understanding Bit Depth Levels for Analog to Digital Conversion

This answer is about studio type audio digitization, creating the typical .wav file. In other specialty areas things may be different. The AD converter has same step size all over its range. Or as you ...

What frequency/bit depth were the Beatles recorded at?

Looking at the specs of the IBM 2401 tape drive from that era, you can see it's at least more complicated than that. The fastest of the 3 models recorded 90 kbyte/s while running the tape at 112.5 ...

How do I check sound card's bit resolution and sampling rate on Linux?

This might depend on which distro you use, so you might need to tweak these commands somewhat. If you look in /proc/asound and do a ls -alh in this directory, you should see a list of cards named ...

What frequency/bit depth were the Beatles recorded at?

There is no way to compare them because one is analog and one is digital. The way to calculate kbps is: bit depth * sample rate * channels Neither vinyl nor cassettes use bit depth or sample rates. ...

Audio ADC vs uncpecified ADC with similar parameters

It depends on the application I guess. For example, a lot of speech processing (and transmission) nowadays is happening in the range that reaches up to 12 KHz or 16 KHz at maximum. Whether you intend ...

Protools 10 what is a 32-bit floating point about?

Yes... bit depth is about dynamic range, but its more about 'smoothness' of your sampling, and the number of discrete levels you can represent. If you draw a wave signal on graph paper, then draw ...
