A WAV file has the potential to hold "more" or "better" data than an mp3. WAVs employ no compression, no loss; they are as close to an exact replica as it is possible to get. An mp3 employs lossy compression to achieve the smaller data size. Lossy compression means that information is actually just thrown away if the algorithm decides no-one would be able ...

No. When you convert a file from .mp3 to .wav, no new information is added: there is no way to regenerate the information that was lost when you created the mp3. All the extra data in the .wav file is redundant.

Usually, an application that plays encoded files (be it audio or video) will need to decode that file to a format that the target interface (be it a video or audio interface) can output on a standard port (like analog or spdif for audio, hdmi or vga for video). Most audio interfaces are waiting for PCM datas. Depending on the OS host of the platform, the ...

MP3 is the 'colloquial' name for "MPEG 1 Layer 3" audio encoding. The purpose of mp3 encoding is to reduce the overall size of an audio data stream whilst maintaining an acceptable level of listening quality. It is implemented using a "codec", meaning that you need an "Encoding" function and a "Decoding" function in order to listen to the audio. The ...

In order to make sound, your computer must drive the speaker with a time-varying voltage. In order to create the time-varying voltage, the computer must send a sequence of numbers to a Digital-to-Analog Converter (DAC). The simplest .wav file just contains a sequence of numbers that are ready to send to the DAC. An .mp3 file is a much more sophisticated ...

I recommend you to start with pulse-code modulation files (.WAV, .AIFF, etc.): https://en.wikipedia.org/wiki/Pulse-code_modulation What is stored in a typical CD-quality PCM file is nothing more than a few metadata markers, and a trunk of stereo data kept as numbers(note, they may be floating numbers or integers). You can view PCM files as a "dump" from ...

These spikes are high frequency components contained in the resulting signal decode. There are two possible reasons for this. Method one uses a low pass filter which removes these components. Method two has a decoding fault. Both of these suggestions are speculative as there is no reference signal to compare.

You cannot get detail from nothing Even though WAV files can hold more detailed sound, that doesn't mean they always do. Converting from MP3 to WAV would be one such scenario, the converter cannot just make up the extra added details to add to the WAV files. It can only remove existing details when compressing. Convert a decent audio file to 16kbps MP3 and ...

I'm building a Passive Mid-Side encoder that might do the trick for you. It has multiple ins and outs, you can monitor each channel with dedicated direct outs, uses quality Jensen transformers, and for now it comes in an attractive box hand made from reclaimed redwood. I'm going to sell a couple of these soon for something less than a grand ($US). There's ...
