Use the hqp5-conv tool (or hqpconv for older versions) to convert long WAV files into HQPlayer’s native polyphase format. It reduces CPU load dramatically.
On a Sunday afternoon, rain on the skylight, he loaded an old mono field recording he’d inherited from his grandfather. The tape was fragile; the capture was honest but rough. He selected a narrow-band de-essing, lifted the lows with a gentle shelf, and applied a small phase-linearizer to tame an unpleasant smear. The crackle, which had once felt like noise, transformed into texture. His grandfather’s laughter, recorded in a living room decades earlier, sat in the mix like a souvenir. Martin felt suddenly cultural lines connecting—record, room, listener, tool—knotted together by small, deliberate choices. hqplayer equalizer
Next, you tackle the treble. You reduce the level of the highest frequency band by a decibel or two, which takes the edge off the sharpness and makes the music sound smoother. Use the hqp5-conv tool (or hqpconv for older
He wasn't just listening to music; he was excavating it. HQPlayer was his shovel. Most audiophiles were content with "good enough." They played their FLAC files through standard players, happy if the bass didn't distort. Elias sought the ghosts in the machine. He wanted to hear the intake of breath between the vocalist's lyrics, the squeak of the pianist’s leather shoe on the pedal. The tape was fragile; the capture was honest but rough
Convolution handles phase correction. IIR only changes amplitude.
He set the device on the kitchen counter between a stack of design magazines and a pot of basil, read the single-page manual, and fed the first high-resolution album into HQPlayer. The room filled slowly, as if the speakers were exhaling. Details he’d never noticed—microscopic echoes in a piano’s tail, the grain of a singer’s consonants—materialized from the air like dust motes lit by a sunbeam. He felt the edges of the music sharpen until they cut the same way a perfect line cut through a plan.
| Do | Don’t | |----|-------| | Use (±3 dB max for cuts, +1–2 dB for boosts) | Boost below 40 Hz (wastes headroom, risks clipping) | | Enable auto-attenuation in HQPlayer’s settings to avoid digital clipping | Apply EQ when upsampling to DSD (requires PCM → DSD, degrades DSD purity) | | Check overall level with a true-peak meter after EQ | Use multiple steep cuts – phase distortion accumulates |
