DAB Audio Processors

Looking for a professional DAB+ audio processor for your digital radio station?
At ProFM Broadcast, we offer professional audio processing solutions designed to improve sound quality, maintain consistent loudness and optimize audio performance for DAB+ digital radio broadcasting.

A DAB+ audio processor prepares the audio signal before digital encoding and transmission. Professional DAB+ audio processing helps broadcasters achieve a consistent station sound while managing audio dynamics and maintaining clarity across different programme sources.

Professional DAB+ Audio Processing for Digital Radio

DAB+ audio processing plays an important role in modern digital radio broadcasting. Unlike traditional analogue FM transmission, DAB+ uses digital audio encoding and multiplexing to deliver radio programmes to compatible receivers.

Professional DAB+ audio processors help prepare the programme audio for the digital transmission chain. Depending on the equipment, processing functions may include automatic gain control, multiband compression, equalization, peak limiting and loudness management.

Correct audio processing can improve the listening experience and help broadcasters make effective use of the available audio quality within their chosen transmission configuration.

Why Use a DAB+ Audio Processor?

A dedicated DAB+ audio processor offers several advantages for professional digital radio broadcasters:

• Consistent loudness: automatic gain control and dynamic range processing help maintain balanced audio levels between music, speech and different programme sources.
• Improved sound quality: equalization and carefully adjusted dynamics processing can enhance clarity, tonal balance and speech intelligibility.
• Multiband compression: independent control of different frequency bands allows broadcasters to shape the overall station sound.
• Peak control: appropriate limiting helps manage audio peaks before digital encoding.
• Optimized audio dynamics: processing can be adjusted to suit the station format, programme content and listening environment.
• Consistent station identity: configurable processing parameters and presets help create a recognizable sound across different programmes.

DAB+ Audio Processing and Digital Audio Encoding

DAB+ broadcasting uses HE-AAC audio coding to transmit digital radio programmes efficiently. The available bitrate and encoder configuration influence the final audio quality received by listeners.

A professional DAB+ audio processor prepares the signal before encoding, helping broadcasters manage audio levels, dynamics and frequency balance.

Audio processing and audio encoding are separate functions, although some broadcast systems combine these capabilities. Selecting suitable processing settings is particularly important when operating at lower audio bitrates, where excessive high-frequency content or aggressive processing may produce undesirable encoding artifacts.

Loudness Control for DAB+ Radio Stations

Maintaining consistent perceived loudness is an important consideration for digital radio broadcasters. Significant differences in loudness between programmes or radio services can reduce listening comfort.

Professional DAB+ audio processing can help manage these differences through automatic gain control, compression and appropriate loudness adjustment.

The preferred processing configuration depends on the programme format, broadcaster requirements and the overall digital transmission chain.

Choosing the Right DAB+ Broadcast Audio Processor

When selecting a DAB+ audio processor, consider the technical requirements of your digital radio station and the characteristics of your programme material.

Important factors include audio input and output connections, processing flexibility, loudness management, digital audio compatibility, remote control options and integration with the existing encoder or multiplex system.

Some processors are designed specifically for digital broadcasting, while other professional broadcast audio processors support multiple transmission platforms, including FM, DAB+ and internet radio.
