USB direct connection for quick file transfer

Transferring files to or from your computer is fast and convenient. Just plug the ICD-PX470 straight into a free USB port for an immediate connection—no USB cable needed.

Expand your memory with the micro SD card slot

The ICD-PX470 comes with 4 GB of memory built-in, which gives you a max recording time of 59 h 35 m when recording in stereo at MP3 128 kbps. You can expand your memory capacity with a micro SD card for up to 32 GB of additional memory—equivalent to over 536 hours (Micro SD 32 GB, MP3 128 kbps) of recording time.

Calendar Search finds the right file quickly

Recordings are marked by date, so you can easily find which ones were made on a specific day. Bring up the calendar to browse through days and find the recording you’re looking for.

Low cut filter eliminates unwanted noise

Filter out low-frequency background noises when you record by engaging the low cut filter. Sources of unwanted noise like projectors, traffic or wind can be filtered out of your recording, so it’s easy to make out voices when you listen back.

Record and listen in Linear PCM or MP3 formats

Choose from two popular file formats when you record. Linear PCM files are larger but capture more detail—ideal for recording music. MP3 files are compressed but require less memory, making them better for recording long lectures or meetings. The ICD-PX470 will also play back MP3 and PCM files, so you can listen to your favorite songs in music player mode.

Transcription playback helps you review recordings

Getting conversations down on paper is easy with the transcription playback mode. Easily fast-forward and rewind through the track, or create cue points that help you find your place quickly. Digital Pitch Control even lets you slow down the playback speed so you can listen more closely to what’s being said.

S-microphone system captures distant or quiet sounds

Now you can record those faint audio sources without capturing excessive background noise, thanks to the high-sensitivity, low-noise S-microphone. Even the sound of birds twittering in the distance can be captured naturally and clearly.

Record and listen in Linear PCM or MP3 formats

Choose from two popular file formats when you record. Linear PCM files are larger but capture more detail—ideal for recording music. MP3 files are compressed but require less memory, making them better for recording long lectures or meetings. The ICD-PX470 will also play back MP3 and PCM files, so you can listen to your favorite songs in music player mode.

Auto Voice Recording reduces background noise

Want to record someone talking? Turn on Auto Voice Recording and the ICD-PX470 will optimize audio capture settings for vocal frequencies. The result is a purer recording with reduced background noise. And when you listen back to the recording, Clear Voice technology cleans up the signal even more for improved clarity.

Adjustable microphone range for clearer voices

Adjustable microphone settings hone in on the sound you want to capture. When you’re recording a single voice, Focus mode captures a narrow field of sound from one direction. When you’re in meetings, the Wide-Stereo mode opens up the range to capture everyone in the room. Choose from four “scene” pre-sets (music, meeting, interview, dictation) to further optimize the audio settings.

Extra-long battery life for extended recording

When recording with the built-in mic at MP3 192/128 kbps, the supplied AAA battery will last for up to 55 hours. That’s over two full days of non-stop recording in between battery changes—perfect for recording at long conferences and events.
