Types of audio format

I'm going to analyze the differents types of audio format: MP3, WAV, AIFF, DSD & MQA.

MP3
If you are interested in having some fidelity in the audio, a decent sound in your files, you should avoid this format. Why? Basically because it is a file that sacrifices the audio quality to minimize the size.

WAV
Waveform Audio Format are just as common, but better for anyone who wants a decent audio format. They are files of higher resolution than MP3. A WAV file is encoded by a medium called PCM (Pulse Code Modulation). A medium that encodes the analog audio pieces and converts them into digital.

AIFF
Audio Interchange File Format is very similar to WAV, it also uses PCM. This format appeared as an answer of Apple before the WAV of Microsoft. Currently, AIFF and WAV are more or less interchangeable. We will see them in online transmission service.

DSD
Direct Digital Stream. Sony and Philips began experimenting with very high quality audio CODEX and the DSD format was the result. Ex: A CD or the Spotify streaming service has bit depth and Sample rates of 16 bit / 44.1 KHz, while the DSD audio formats provide 1 bit / 2.8224 MHz. A DSD file samples a whopping 2,822 .400 times per second and every time you get the samples it produces 1 bit of information producing incredible detail. There is DSD 64 and DSD 128.

In short, this format is one of the best that exist.

MQA
Master Quality Authenticated is a revolutionary end-to-end technology that offers studio quality in files small enough to be used both in streaming online and for downloading. But being authenticated, the user can be sure that he is listening to exactly what the artist interpreted in the study. With an important practical quality: it is compatible with the vast majority of devices.

Foley Effects

Imagen
Foley effects are sound effects added to the film during post production (after the shooting stops). They include sounds such as footsteps, clothes rustling, etc. The technique is named after Jack Foley, who established the basic modern techniques still used today. Like most terms that are named in honour of a person, it is customary to spell Foley with a capital "F". The boom operator's job is to clearly record the dialogue, and only the dialogue. At first glance it may seem odd that we add back to the soundtrack the very sounds the sound recordists tried to exclude. But the key word here is control. By excluding these sounds during filming and adding them in post, we have complete control over the timing, quality, and relative volume of the sound effects. The Foley artists can clearly see a screen which displays the footage they are to add sound fx to, and they perform their sound effects while watching this screen for timing. The actions they perform can...
