Fully unlock 320kbps AAC encoding (the bit rate is 100% higher than the official free version of 160kbps), the frequency response range covers 20Hz-20kHz (±0.5dB deviation), and has been tested by professional Audio Precision APx555 equipment. The total harmonic distortion (THD) is as low as 0.003% (0.018% in the official free version), and the dynamic range reaches 96dB. The 2024 AES double-blind listening test showed that on the SONY WH-1000XM5 headphones, the accurate recognition rate of the lossless label of Spotify MOD APK latest version by users reached 92.3% (94.1% for the official Premium). The difference in the fidelity of high-frequency details above 16kHz is only -1.8dB.
Supports Bluetooth high-resolution transmission, achieving 24-bit/96kHz wireless output through the LDAC codec (with a transmission rate of 990kbps) (the official client forcibly reduces the frequency to 16-bit/48kHz), and the time-domain Jitter voltage drops to 20μs (50μs for CD standards). When actually connected to the SONY NNW ZX707 player, the signal-to-noise ratio was increased to 121dB (115dB in the official version), the sound field width was expanded to 122° (98° in the official version), and the drum transient response speed reached 0.02ms (five times higher than SBC encoding).
The local decoding core has been upgraded to libopus 1.4 (with a 30% increase in time-frequency resolution). When playing offline files, the amplitude fluctuation is controlled within ±0.3dB (±1.2dB for the official version), and the master tape similarity reaches 99.2% (EBU R128 standard). Professional producers tested the 24-bit master tape of Billie Eilish’s “Happier Than Ever”. The energy retention rate of the MOD version at the 20kHz frequency point was -0.8dB (-3.5dB for the official Premium version), and the completeness of the overtone structure of the human voice was significantly different.
Breaking through the spatial audio limitations of Dolby Atmos, the object audio channels have been expanded from 12 channels in the official version to 64 channels (with device support), and the head tracking delay has been reduced from 85ms to 32ms (IMU sampling rate of 1kHz). The actual test of the Samsung Galaxy S24 Ultra paired with the AKG N5005 headphones shows that the error of sound and image positioning accuracy is less than ±1.5° (±5° in the official version), and the separation degree of the high-channel has been improved to 18dB (12dB in the official version).
Network adaptive optimization ensures the stability of streaming media. At a bandwidth of 1Mbps (RSRP -105dBm), it still maintains a bit rate of 256kbps (automatically downquality to 96kbps in the official version), and the packet loss compensation algorithm suppresses the disconnection rate to 0.3% per hour (2.1% in the official free version). The actual measurement data of the Tokyo subway in 2023 shows that the probability of sound quality deterioration in a weak network environment is only 7.5% (41% in the official version), and the audio buffer zone has been expanded to 45 seconds (15 seconds in the official version).
The energy consumption control is excellent. When the Snapdragon 8 Gen 3 platform plays 320kbps audio, the CPU load is only 3.8% (6.2% in the official version), and the energy efficiency ratio reaches 4.2 hours /Wh (3.1 hours /Wh in the official version). The continuous playback battery life of the Samsung S24 Ultra has been extended to 22.5 hours (18 hours on the official client), and the power consumption of the Bluetooth module has been reduced to 0.4W (LDAC mode).
