Formatos de Señal de Audio

In audio engineering, a balanced audio signal is a type of audio signal that is transmitted over two conductors, with each conductor carrying an identical signal, but one signal is inverted. This inversion is used to cancel out noise and interference, making it ideal for longer cable runs.

A non-balanced audio signal is transmitted over two conductors, one carrying the audio signal and the other serving as a ground reference. This single path signal transmission makes it prone to noise and interference, especially over long distances.

The process of canceling out noise and interference in an audio signal by summing the original signal with an inverted copy of itself.

The 'hot' signal in a balanced audio cable is the signal that carries the original audio waveform. It's transmitted over the top conductor.

The 'cold' signal in a balanced audio cable is an inverted copy of the original audio signal. It's transmitted over the bottom conductor.

The exterior braided shield or mesh of a non-balanced audio cable is used as the return path for the signal. However, this can be vulnerable to noise and interference.

Non-balanced audio signals are susceptible to interference because of the power imbalance between the two conductors, making them more vulnerable to electromagnetic noise picked up from the environment.

Home audio systems, semi-professional audio equipment, and some consumer-grade devices typically use non-balanced audio signals. They are generally simpler and cheaper to implement than balanced audio.

Phantom power is a method of providing DC power to microphones through the balanced audio cable. This is essential for condenser microphones that require external power to operate.

The standard voltage of phantom power used in audio equipment is +48V. This provides enough power to operate most condenser microphones.

Live sound consoles, also known as mixing consoles, are audio mixing desks primarily used during live performances and events. They usually have a larger number of input channels and features designed for live mixing.

Recording consoles are audio mixing desks designed for recording studios. They usually have fewer input channels than live sound consoles but focus on high-quality audio processing and recording capabilities.

Chassis connectors are built-in connectors physically integrated into the structure of a sound system. They typically include connections for audio input and output, as well as other functionalities like power and control.

Output modules or sub-groups in live sound mixing consoles provide a pathway to route audio signals to separate outputs or groups for various recording purposes. They include a section for recording audio signals to a separate device.

Mixing consoles, whether live sound or recording consoles, are designed to be flexible and customizable, allowing audio engineers to customize routes and processing for different audio signals. This can be achieved by using patch bays, which are connection points for audio signals.

A control room is a dedicated space in a recording studio where the audio engineer monitors the mix during recording and mixing. It features a separate set of speakers and controls for accurate monitoring of audio signals.

VU meters, short for Volume Units meters, are analog meters used in audio engineering to measure the average level of an audio signal. They are typically calibrated to the standard dBFS (decibels relative to full scale) scale.

Peak meters, also known as PPM (Peak Program Meter) or peak hold meters, are devices that measure the highest level of an audio signal, even brief peaks or transients. They provide a visual indication of the peak level to help avoid clipping and distortion.

The dynamic range of an audio signal is the difference between the highest and lowest levels in the signal. It's a measure of how much variation exists in the audio levels.

A control panel, situated in a central location, provides a comprehensive view of the audio signals processing and routing for the audio engineer. It allows the control of settings and parameters across multiple channels or sections of the console.

VU (Volume Units) is a standard unit of measurement for audio levels. VU meters are widely used in audio engineering to monitor and control audio levels.

A layer in a control panel refers to a specific level of control or access to specific functions. Different layers allow the engineer to navigate through different sets of parameters and settings within the console.

A film studio's control room often features an external processing setup using dedicated hardware and software, allowing for advanced sound effects and audio manipulations during post-production.

Film studios prioritize standardizing the overall sound experience between the mixing room and the actual movie theatre. This ensures consistency in audio levels and frequencies across different viewing environments.

DJ mixers are designed for live DJ performances, featuring multiple stereo audio inputs that are typically non-balanced. They prioritize instant control over mixing and transitioning between audio sources.

MIDI (Musical Instrument Digital Interface) facilitates communication between electronic instruments and computers, enabling control of virtual instruments and software effects. VST (Virtual Studio Technology) refers to software plugins that emulate real-world audio effects and instruments, offering a vast range of sound processing options.

Film studios often use dedicated cinema mixing rooms equipped with advanced audio processing equipment and a large screen for viewing the film in its finished form.

Modern film studios are increasingly focused on minimizing the difference between the sound experience in the mixing room and the movie theatre. This ensures that the sound quality is consistent across both environments.

Radio studios typically use specialized monitoring setups to ensure the sound quality is appropriate for radio broadcasts. This may involve using specific speakers, microphones, and recording equipment designed for broadcasting purposes.

DJ mixers often lack features such as group and auxiliary buses, which are commonly found in live sound and recording consoles. These features are less essential for the immediate mixing tasks of DJing.
