Are any special steps needed to combine two or more audio files without quality loss?

Mixing audio in a computer is very analogous to how sound mixes in the real world. In the real world, sound is simply pressure waves that cause vibrations in our eardrum that get converted to what we ...

Convert Mono to Stereo before or after editing?

I just came up with a rule of thumb. I don't know if it is is really any good or not, but maybe worth considering. If you are taking things away (cleanup) better to do it in mono. If you are adding ...

How lossless is my lossless music?

Audio sampled at 44.1 kHz (like normal audio CDs) can in theory contain content up to the Nyquist limit of 22.05kHz. However, you need a filter to remove all content above that limit, otherwise it ...

Digitize vinyl on PC (TT > Stereo Amp > USB Audio Interface > PC recording software)

Use the Marantz as your pre-amp. Route the audio out of one of its 'Recorder' outputs. This should give you consumer-level output, nominally -20dB. Input to the Behringer on a switchable input mic/...

Is there any loss of audio quality when converting from digital to analog audio?

Yes, any analog transition or transmission has quality loss. How noticeable that loss is depends on a variety of factors including the quality of the DAC (digital to analog converter), the quality of ...

Converting audio recording to numeric values representing how loud the audio is at a given time

You would rather turn to a program like Matlab or its open source equivalent Octave. Open your mono-channel audio data as a vector (using wavread for instance), and turn each sample value to its ...

Which methods exist for converting stereo to mono?

Off the top of my head.. Sum - Adds Signals; any sounds present in both signals are reinforced by a varying amount, depending on how in-phase they are. Subtract - Subtracts one signal from the other(...

Backing up DVDs on computer and change the audio tracks from 192 to 384 kbps

It is impossible to upsample the bitrate. Your files have already lost the info from being compressed to 192. It looks to me as if the AC3 is going to give you a similar if not slightly more ...

Does "converting" mp3 file two times, makes a difference?

Yes, there will be a difference. Mp3 is a lossy codec that deteriorates with every generation. It's bad practice to use mp3 (or lossy compression in general) at any stage where the audio may yet be ...

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 ...

Converting -10dbm to dbu?

First convert dbm to Watts using the following: Pw = 10^(Pdbm/10) / 1000 Pw = 10^(-10/10) / 1000 = 0.0001 Watts So the max output power is 0.0001 Watts, and the output load impedance is 10 kOhm. We ...

Is it safe to convert rca to xlr

Assuming that the preamp outputs are line level, then yes it is perfectly safe to do this. You will wire the connection up as follows: Ground (RCA) to Pin 1 and 3 (XLR) Signal (RCA) to Pin 2 (XLR) ...

from Flac to wav

FLAC is lossless compression. During compression, you can set a compression option: setting this to a higher level creates a smaller file that is still lossless by taking more time to process the file....

How do you convert sound decibel (dB) measurements to a common loudness scale?

There is no formula you can use to make this conversion. It is unlikely your webcam would be suitable as a sound sensor due to the processing involved in detecting and multiplexing the audio into the ...

Do mobile phones etc. convert stereo music to binaural for earbud listening?

No, they do not. It might be possible to cross-connect a short delay across the left and right channels in order to simulate two speakers in front of the head, but this is generally not done. The left ...

From this wikipedia article: Unlike a WAV file, a VOX file does not contain a header to specify the encoding format or the sampling rate, so this information must be known in order to play the ...

Any reason not to convert WAV to FLAC and save some disk space?

I'm struggling with this issue now, as well. The one downside to Flac, that I can see, is that it doesn't support media cues. One benefit to recording in Wav is that I can record a lot of audio at ...
