Types of microphones

Resultado de imagen de microfono listón png

There are three types of microphones, however, it must be taken into account that each of these types could work for one type of audio and not for another type of audio. They are:

  • Condenser: typical microphones of the studios. In turn, they are classified into two subtypes: large diaphragm condenser and small diaphragm condenser (or pencil); The difference is that the former captures the signal more broadly while the latter captures it in a more localized way. For its operation, it needs an external power: Phantom Power (+ 48V), present in the interface of our audio. They offer a detailed sound since it has a high sensitivity to sound.

  • Dynamics: These are the classic ones and they are even included with the karaoke system. They are quite cheap and very durable, so they are cheap. They need the source to be close and they do not work well with the high frequencies, however, they resist the high sound pressures.

  • Ribbon: They are very expensive due to the material used and, therefore, they are also extremely fragile; They have a small thin sheet of metal, which can be easily broken if it receives high levels of sound pressure or with the use of Phantom Power.

Each of these microphones can have one or more integrated polar patterns, which are what allow the microphone to capture the sound.

  • Cardioid: only captures the sound that comes from the direction in which the microphone points; rejects the sound coming from behind.

  • Figure 8: Capture the sound coming from the front, from the back and from the side; reject the sound of the sides.

  • Omni: detects the signal in all its circumference.

Lucas Vidal

Lucas Vidal is a spanish composer and he live in Los Angeles. He born in Madrid and started to play his first instrument when he was 3 years old: the piano. Also he played the violin and the flute. And he always tried to compose music with those instruments since he really liked composing. He get influenced by his grandfather a lot who was one of the founders of the record company "Hispavox" and one of the artist of this recording business gave a prize to Lucas Vidal after a time, which make Lucas Vidal so happy and proud.                  When he was 16 years old he went to Berklee College of Music in Boston because of a scholarship that he won and that's where he discovered that there is a degree for music for films. He even achieve to make music for a film when he was 21 years old while he was still studying. Although he had break since he was diagnosed with cancer and he had to stop his studies to treat with chemother...

Types of audio format

Imagen
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 th...
