Radio Mast provides a complete ecosystem for online AAC streaming
Radio Mast provides AAC stream hosting for radio and live events. Our unique streaming network globally distributes your stream to provide reduce dropouts and provide a stutter-free experience for your listeners.
AAC offers superior sound quality at lower bitrates, which both lowers delivery costs and improves audio quality for your listeners. AAC is compatible with all modern Android and iOS devices, smart speakers, smart TVs, and other devices. AAC can give your radio station an edge with superior sound quality.
High-Efficiency AAC (HE-AAC) is an extension to the AAC codec, which further optimizes the codec for low-bitrate streaming (less than 128 kbps). Low bitrate streams are more reliable on mobile devices as mobile network bandwidth can vary significantly depending on cellular coverage. HE-AAC v1 provides improved sound quality at lower bitrates by removing high frequencies during encoding, and then resynthesizing these during playback using a technique called Spectral Band Replication (SBR).
HE-AAC v2 (AAC+) adds another optimization for low bitrates called "Parametric Stereo", which encodes the audio as a single mono channel, which is used to synthesize a stereo signal. The result is that convincing stereo audio is achieved at much lower bitrates than were previously possible, although with lower reproduction accuracy. This tradeoff makes AAC+ an excellent choice for streaming radio.
