FAQ
What does Lacquer do to verify audio quality?
Lacquer decodes and analyzes the audio data of imported files directly on your device. It examines aspects like the top-end frequency response and its consistency across the track to determine if the file is genuinely high-resolution or potentially upscaled.
Does Lacquer upload my audio files?
No, Lacquer performs all audio decoding and analysis locally on your phone. Nothing is uploaded to any servers, and there is no account required to use its core verification features.
How does Lacquer present its findings?
Lacquer provides a verdict that indicates if a file 'may be upscaled' rather than definitively calling it 'fake'. It shows the specific numbers and measurement lines used for its decision, allowing users to review the evidence.
Can Lacquer help with headphone sound tuning?
Yes, Lacquer allows you to import headphone measurement files for parametric EQ correction. You can also manually adjust up to 10 EQ bands or select preset sound styles, with automatic preamp adjustment to prevent clipping.
What audio file formats does Lacquer support?
Lacquer can play FLAC, ALAC, WAV, AIFF, MP3, AAC, and m4a files from your personal library. It also supports gapless playback and crossfade for a seamless listening experience.
How does Lacquer handle subscription plans?
Lacquer offers 'Lacquer Pro' through both yearly and weekly subscription plans, priced at $0.99. These plans likely unlock additional features or enhance the existing functionality beyond the free tier.
Does Lacquer have ads?
Yes, Lacquer contains advertisements. As a free application with in-app purchases, ads are part of its monetization model to support its development and availability.
What devices is Lacquer compatible with?
Lacquer is designed for use on Apple devices, including the iPhone, iPad, and Apple Watch. This broad compatibility ensures users can verify their audio across multiple Apple ecosystem devices.
