Three high-fidelity microphones for best-in-class audio recording
Several key components are needed to record sound as naturally as possible in studio-like audio quality: high signal-to-noise ratio, highly dynamic microphones to capture soft tones as well as loud drums, a high-quality microphone suspension to avoid pickup of grip noise, a strong left and right channel separation for human ear live-like effect.

Stereo MP3 and PCM recording for clear playback and easy file sharing
Capture your recordings in stereo MP3 or PCM format. The popular MP3 file format allows you to play back your files virtually anywhere and simply share them with others. The PCM (WAV) format allows stereo recording of lossless, uncompressed sound in CD-like audio quality.

8 GB internal memory for up to 88 days of recording
Capture and store up to 88 days of continuous recording thanks to the 8 GB of internal memory. A microSD memory card slot for up to 32 GB of additional memory guarantees virtually unlimited recording capacity.

Rechargeable Li-ion polymer battery for extra-long recording
The high-capacity Li-ion polymer battery can be easily charged through a standard USB C jack. This guarantees extended battery life for extra-long recording up to 36 hours, ensuring that your recorder will always be ready to work when you are.

Free smartphone app for remote audio control
Control your audio recorder using your smartphone, even from a distance. The Philips VoiceTracer app makes recording events such as lectures much easier and more convenient. You can place your recorder in the front of the room near the speaker, take a seat at the back, and still control recording comfortably and without interrupting the lecture. The Philips VoiceTracer app can be downloaded for free from the Apple App Store or Google Play Store.

Large color display for clear recording status information
The large color display offers sharp images, making it easier to see and read everything at first glance. The clear user interface supports seven languages and is optimized for easy, intuitive operation.

Audio scences for automatic perfect audio settings in any situation
The Philips VoiceTracer comes with preset scenes which automatically adjust the recorder’s audio settings depending on what you want to record, whether it is notes, audio for speech recognition, interviews, lectures, music or meetings.

Smart recording and playback functions for best recording results
Smart recording functions make it even easier to achieve stunning audio results. The pre-recording and timer functions make sure you don’t miss a single bit. Voice-activated recording is a convenient feature for hands-free recording which pauses recording when you stop speaking and resumes automatically when you begin speaking again. Recordings can be edited by overwriting a part or adding a new recording at the end. Long recordings can be split automatically or manually into separate files for easier editing or sharing. Smart playback functions, such as bookmarks and filters, also make it easier and quicker to find the recording you are looking for.

Automatically convert your recordings to text, up to three times faster than typing
Put an end to tedious typing and create text documents directly from recorded audio files. Using the Sembly Speech-to-Text Software is at least three times quicker than typing up the document yourself. Simply record your notes, interviews or meetings, upload them to Sembly, and receive a written document almost instantly.

Automatic meeting minutes with multi-speaker transcription for easy following up
If you want to record meetings, Sembly Speech-to-Text Software creates automatic meeting minutes, so you can focus on your conversation and not get distracted by having to take notes. Thanks to multi-speaker identification you can clearly identify who said what.

Easily share your voice or meeting recordings with colleagues, family or classmates
Sembly allows to save transcriptions on your computer in PDF or markdown format. You can easily share your voice recordings and transcripts with colleagues, family or classmates by simply sending them a link. For increased privacy, you can add a password to your link.

How to use

Place the recorder near the main sound source for best results, or use the smartphone app to position the device at the speaker and control recording remotely. Choose stereo MP3 for easy playback and sharing or PCM (WAV) for lossless, high-quality recordings. Use pre-set audio scenes to automatically configure the recorder for notes, speech recognition, interviews, lectures, music or meetings. Start, stop and manage recordings via the device controls or the Philips VoiceTracer app and transfer files to a computer over the USB Type‑C connection or via the app for sharing.

Recommendations

For accurate speech-to-text conversion and clear multi-speaker transcription, place the recorder within 1–3 meters of speakers, avoid covering the microphones, and upload high-quality WAV or MP3 files to Sembly after recording. Use a microSD card for extended sessions and keep the battery charged before long events.
