Bit-Perfect Audio Detector 1.1.0

What's new in 1.1.0

• USB Audio Class: the USB DAC card now shows whether the connected DAC is UAC1, UAC2 or UAC3, next to its name (for example, "Connected: HiBy FC3 (UAC2)").
• DSD through bit-perfect: on phones with bit-perfect confirmed, the Bit-Perfect Support card now says how far DSD can go through it (DSD64, DSD128 or DSD256, if the DAC supports DSD), or that DSD files will be decoded to PCM.
• Reports from phones that need a DAC: phones that can only confirm bit-perfect with a USB DAC connected (like the Pixel 9a) now explain it, and "Send report" stays disabled until a DAC is connected, so every report from them has a confirmed result.
• The app's version is now shown at the bottom of the screen.

Bit-Perfect Audio Detector 1.0.5

What's new in 1.0.5

• Firmware version: reports now include the phone's firmware version (build number), which can differ by region. The website shows it in a new column, with every version reported for each model.
• USB Audio Class: reports include whether the connected DAC is UAC1, UAC2 or UAC3, shown next to its name on the website.
• More accurate results without a DAC: on phones whose system carries the audio configuration of several chips, the app now reads only the phone's own.
• The suggested music apps are now listed in alphabetical order.
• You can now send up to two reports every 24 hours, this is to avoid spam (it was one every 48 hours).

What's new in 1.0.4

Three more music apps with native bit-perfect support in the "Compatible apps" card: Audilux Music Player and jetAudio Hi-Res Music Player and LastWave. If they're installed, the app checks them; if not, it suggests them with a link to Google Play or to its own website when it's not available at the Play Store.

Bit-Perfect Audio Detector 1.0.3

What's new in 1.0.3

New "Ask the manufacturer" card: on phones without bit-perfect support, the app gives you a ready-to-post draft (with your phone's details and what the app found) and opens your manufacturer's community forum, in your language when there is one. The app sends nothing: you copy the text and post it yourself.

Bit-Perfect Audio Detector 1.0.2

What's new in 1.0.2

• New name: the app is now Bit-Perfect Audio Detector.
• New icon: a USB DAC with the stepped waveform of PCM samples.

No changes to how the app detects bit-perfect support or sends reports. The package name stays com.bitperfect.detector, so it installs as an update over 1.0.1.

Bit-Perfect Audio Detector 1.0.1

Maintenance release, getting the app ready for Google Play.

Changes

• The "Send report" card is hidden on Google Play's automated test devices (Firebase Test Lab) and on Android emulators, so they no longer send reports that don't come from real phones.

Nothing changes for regular users: if you have 1.0.0 installed, this version updates it normally.

Bit-Perfect Audio Detector 1.0.0

First public release of Bit-Perfect Detector, an Android app that tells you whether your phone supports Android's native bit-perfect mode and Hi-Res audio through a USB DAC.

What it does

• Bit-perfect support: reads the audio configuration the manufacturer installed on the phone and, with a USB DAC connected, confirms it with Android's own API (AudioMixerAttributes, MIXER_BEHAVIOR_BIT_PERFECT).
• Hi-Res audio: shows the maximum resolution the phone declares for the USB output and the one Android accepts with your DAC.
• USB DAC: detects the connected DAC; results update automatically when you plug it in or unplug it.
• Compatible apps: lists your installed music apps that use Android's native bit-perfect mode, and suggests others from the Play Store.
• Send report: sends your results anonymously, so your phone can be added to the public table of phones.
• Available in 10 languages: English, Spanish, German, French, Italian, Portuguese, Turkish, Japanese, Korean and Hindi.

Privacy

Reports are anonymous: they don't include your name, email address, accounts or anything that identifies you, only data about your phone and its audio. The app uses the internet only to send the report when you tap "Send", and you can review everything before sending. The report server is open source and stores nothing. See the privacy policy.

Requirements

Android 14 or later (native bit-perfect mode was added in Android 14). A USB DAC is optional, but needed for a definitive result.

Installation

1. Download Bit-Perfect-Detector-1.0.apk below.
2. Open it on your phone and allow installing apps from that source if Android asks.
3. If you installed the previous APK where reports where sent through your email, please update it by installing the same APK below.
4. Don't forget to submit your report!.
