Zoom H1 Handy Recorder is a mobile sound recording device. When connected via USB and then turned on, the user can choose between:

  • USB card reader
  • USB audio card

Press the big red record button to select the mode. Both modes work well with Gentoo, even with a deblobbed kernel.

Modes

USB card reader

This modes gives access to the inserted memory micro SD card, or built-in memory when card is not present.

USB audio card

In this mode, the device functions as an external sound card, and works well with ALSA.

Input comes from H1's built-in high quality stereo microphone. Recording volume can be adjusted with +/- INPUT LEVEL buttons.

Output is sent to H1's LINE OUT mini-jack. Playback volume can be adjusted with +/- VOLUME buttons.

The following kernel option is enough:

CONFIG_SND_USB_AUDIO=y

lsusb should show:

Bus 001 Device 024: ID 1686:0045 ZOOM Corporation H4 Digital Recorder

aplay --list-devices gives:

card 2: H1 [H1], device 0: USB Audio [USB Audio]
 Subdevices: 1/1
 Subdevice #0: subdevice #0

Then you can select H1 as the recording device in most programs. If your audio program lacks a drop-down selection and requires specifying the device, you can write:

iec958:CARD=H1,DEV=0
