vPlayer HiFi Classic is a standalone edition purpose-built for iPhone 7 ~ iPhone X, targeting iOS 15 ~ 16 (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 hi-fi 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 locked to the 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 176.4 kHz or 352.8 kHz 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). ▸ Samba / NAS Streaming — Browse and stream high-resolution audio straight from your NAS over Wi-Fi, with smart caching so only the album or ISO in use is held on the device. ▸ 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 Minimum-Phase conversion. SRC and FIR are mutually exclusive — one clean path, no double-processing. ▸ Formats — MP3 · AIFF · M4A (Lite). Upgrade to Pro for studio-grade WAV / FLAC / DSD (DSF, DFF) native playback. ▸ Room EQ — Measure your room with a sine sweep, then layer automatic correction EQ on top of your own EQ. Warm / Neutral targets. ▸ 10-Band Graphic EQ — ±12 dB manual adjustment with a per-band reference guide. Instant response, zero latency. Toggle on/off directly from the signal chain bar. ▸ Parametric EQ (PEQ) — Full 10-band parametric equalizer: frequency, Q, and gain per band, with peaking, low-shelf, and high-shelf filters. Includes a live frequency-response curve. 13 Music Genre Presets — Classical, jazz, vocal, rock/pop, and folk tone shaping, crafted for vPlayer. ▸ Clock & Buffer — Control IO buffer duration (Auto or manual 256–4096 frames) to reduce jitter coupling with your DAC's clock. ▸ Output Covered — Built-in speaker, wired headphones, AirPlay, Bluetooth, and external USB DAC. vPlayer detects your active route and matches the hardware sample rate automatically. ▸ Hands-On Signal Chain — DSD · MEM · SRC ⊕ FIR · EQ/PEQ · DITH.

Real-time route detection shows your output device. ▸ Smart Invert — Invert the whole interface for a light look, handy on OLED panels and for long listening sessions. ▸ Lab — An experimental tools panel: sampling-rate reference, room EQ, lossy-source enhance (pre-echo / exciter), callback & cache monitors, and a switch to show or hide the Pro entry. ▸ Drag album folders via Finder file sharing into the app's Documents folder.
