vPlayer HiFi Youth

vPlayer HiFi Youth — is a standalone edition purpose-built for iPhone 7 through iPhone X, targeting iOS 15 (with compatible iPad support). It retains the core audio playback features only and the purpose is to turn your retired iPhone/iPad into a dedicated hifi player. If you own a newer iPhone or iPad, please search for "vPlayer HiFi" — that app will continue to receive ongoing updates and improvements. Features: ▸ Bit‑perfect — Custom AudioUnit pipeline with hardware sample‑rate. vPlayer matches your source rate so the system never touches your signal. ▸ Native DSD Playback — DSF and DFF, decoded through a custom engine with 4 selectable FIR decimation filters (Steep / Extended / Balanced / Conservative). Choose 176.4kHz or 352.8kHz output. No transcoding, no compromise. ▸ SACD-R ISO Decoder — Native Scarlet Book TOC parser. DSD64/128 playback with selectable decimation (176.4 kHz or 352.8 kHz). ▸ Memory Playback — Preload entire tracks into a dedicated 300 MB memory buffer — enough to hold a full CD‑length album or a high‑rate DSD track. Eliminates jitter from live file I/O. ▸ Polyphase SRC + FIR Upsampling — 6 SRC algorithms from Linear to Sinc‑512 tap with Kaiser‑windowed polyphase resampling. Independent FIR upsampling at 2× / 4× / 8× with selectable tap count (31 / 63 / 127) and homomorphic Minimum‑Phase conversion. SRC and FIR are mutually exclusive — one clean path, no double‑processing. ▸ Formats — MP3 · AIFF · M4A (Lite).
