Record up to 57 hrs of audio (MP3 128 kbps) with exceptional battery life that makes it possible to record for long periods of time.

Built-in USB connector lets you plug in to your PC.

Auto Voice Rec reduces ambient noise for clearer recordings
Want to record someone talking? Turn on Auto Voice Recording and the ICD-PX370 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.

Scene Select lets you optimize settings for music, meetings, and more
Choose from four 'scene' pre-sets (music, meeting, interview, dictation) to optimize the audio settings.

Expand your memory with the micro SD card slot
The ICD-PX370 comes with 4 GB of memory built-in, which gives you a max recording time of 59hrs 35m when recording in stereo at MP3 128 kbps. You can expand your memory capacity with a micro SD card for up to 32 GB2 of additional memory —equivalent to over 536 hours (Micro SD 32 GB, MP3 128 kbps) of recording time.
