Voice Loggers and Audio Recorders Information

Show all Voice Loggers and Audio Recorders Manufacturers

Voice loggers and audio recorders are used to locate, retrieve, duplicate and/or distribute audio voice or data information from single system environments to large multi-channel networked systems. Voice loggers and audio recorders are used in call centers, public safety dispatching, technical support centers, and aircraft cockpit voice recording systems. Voice loggers and audio recorders are also used to record client or customer conversations for quality control and workplace performance optimization. Typically, these systems use digital audio recorder technology to compress the signal for large storage capacity, quick retrieval and playback of stored data, and maintenance of records.


Voice loggers and audio recorders may be voice-activated, work in a continuous recording mode, or be operated manually. Voice loggers are often used to provide sample calls for training new employees. There are some legal issues that must be addressed before implementation. In the United States, the Federal Communications Commission (FCC) recommends that businesses using an audio recorder notify customers by using a beep tone at particular intervals.


Voice loggers and audio recorders can be provided as multichannel systems, typically offering from four up to 32 channels for managing incoming calls or conversations. Multichannel logging can provide connections to phone lines, two-way radios, broadcast audio, and microphones. Voice loggers and audio recorders can also come with computer-based applications for storing digital audio signals. A streaming audio recorder uses a personal computer’s (PC) built-in microphone or an external device to record and play streaming audio in mp3 or Windows Media (wma) format.


Voice loggers and audio recorders are vital tools in emergency response or recreating the scene of an accident. The U.S. Transportation Safety Board uses robust voice loggers, known as black boxes, to monitor crew conversations in commercial aircraft. In the case of a crash or other onboard emergency, the voice cockpit recorder can provide essential information to understand what went on right before the accident. The voice cockpit recording may also offer the only clues in the event of a catastrophic crash that kills the crew and passengers.

  • Audio Amplifiers and Preamplifiers

    Audio amplifiers and audio preamplifiers are used to increase the amplitude of sound signals.  Preamplifiers or preamps are designed to amplify low-level signal from a high-impedance device such as a microphone or instrument pick-up. After pre-amplification, the signal is sent to a power amplifier or amp, which provides the higher current necessary to drive the speakers.

  • Audio Connectors

    Audio connectors are used to affix cables to other audio equipment, providing electronic signal transference and grounding protection.

  • Audio Headphones

    Audio headphones are small speakers worn over the ears to isolate sounds for the listener.

  • Audio Microphones

    Audio microphones are designed for sound reception and recording applications (speech and music).

  • Audio Mixers and Consoles

    Audio mixers and audio consoles are units that combine signals from microphones and/or line level sources to produce a combined signal or signals.

  • Audio Switch Matrices

    Audio switch matrices are electronic switching instruments for interfacing audio signals in scanning, recording and analysis systems.

  • Digital Audio Systems

    Digital audio systems electronically record and store audio signals such as voice, music, alarm, and security messaging for broadcast, editing, monitoring, and playback.

  • Headsets

    Headsets are designed to hold earphones to a user’s head for radio or telephone communications.  They include transducers and a transmitter, and are designed to receive audible signals from a source such as a portable media player or audio amplifier. Often, headsets are bundled with microphones for two-way communication.  The main benefit of headsets is that they let users listen privately, and make it easier to hear in noisy environments.

  • Speakers

    Speakers produce and transmit sounds carried by electrical or radio signals.  This product category is primarily for industrial and OEM speakers rather than those for home use.
