Television viewers constantly reach for the remote. Commercials are louder than programs. Channels broadcast at different levels. Film soundtracks swing from whispered dialog to explosive action sequences. Switching from broadcast to Blu-ray or streaming introduces another level mismatch. Every transition forces a manual volume adjustment — and the inconsistency erodes the perceived quality of the product.

Auto-Volume maintains a consistent listening level automatically. It attenuates loud passages and lifts quiet ones, keeping the output within a comfortable range regardless of source, channel, or content type. Loud commercials are brought in line. Whispered dialog becomes audible. The dynamic intentions of the original content are preserved — quiet moments still feel quiet, and dramatic moments still feel dramatic — but the overall level stays where the viewer set it.

Why conventional approaches failed

Earlier auto-volume implementations used simple one- or two-band compressors with short attack times and extremely long release times. The result was audible breathing — a slow, unnatural swelling of the background level after loud passages ended. The compression was noticeable, unstable, and annoying enough that many users turned it off.

Auto-Volume uses a 3-band compressor architecture that processes low, mid, and high frequencies independently. This prevents bass-heavy content from modulating the entire signal and eliminates the cross-band artifacts that made earlier approaches audible. The release time is set short, allowing compression to recover instantly when it's no longer needed. There is no perceptible breathing or pumping.

Transient preservation

Auto-Volume maintains more than 6 dB of headroom above the target output level. This headroom absorbs transient peaks — sharp attacks in music, sudden effects in film — without clipping. The transients are intentionally preserved rather than removed: shortening the attack time to eliminate them would degrade the transient response and audibly reduce sound quality.

Also increases maximum volume

Beyond leveling, Auto-Volume is also effective for increasing the perceived maximum volume of small speaker systems — laptops, personal audio devices, and compact TVs where louder output is desirable even at the cost of some dynamic range. For applications where maximum loudness is the priority rather than leveling, VoluMax3 provides a more aggressive compression approach.

Best paired with PRISM

Auto-Volume delivers optimal results when the speaker system has a flat acoustic power frequency response as its baseline. PRISM equalization establishes that baseline, ensuring that the compressor operates on a tonally accurate signal rather than compensating for speaker deficiencies.

Where Auto-Volume fits

Auto-Volume is designed for TVs, soundbars, and small audio systems where level inconsistency between sources is a primary user complaint. It operates upstream of the volume control, processing the signal before the user's volume setting is applied.
