The H2 Handy Recorder is a handheld digital audio recorder from Zoom first announced at the NAMM Show in February 2007. It records very high quality digital stereo or 4-channel audio on a hand-held unit, and has been called "the studio on a stick." [1]
Included in the retail box are an SD card, desk stand, handle for putting the H2 in a microphone stand, wind screen, 3.5mm TRS to RCA cable, earbud headphones, USB cable and power adapter.
The H2's microphones, functionality, and use of standard USB and SD interfaces make it suitable both for recording high-quality sound and in many speech applications. The H2 has been cited by various oral history associations, such as Oral History Association [2] and Vermont Folklife Center [3] as an affordable option for recording narrator interviews.
The H2's rate of data transfer via the USB 2.0 port is "full speed" of up to 12 Mbit/s, the same as USB 1.1 and much slower than the widely available USB 2.0 Hi-Speed of 60 Mbit/s. [4]
The H2 can be powered either by two standard AA batteries or a power adapter. Recording time with low self-discharge 2000 mAh NiMH batteries is about 6 hours for mp3 bitrate set to 128 kbit/s.
The H2 can record in WAV format (at 96, 48, or 44.1 kHz in either 16 or 24 bit depth). Recording to compressed MP3 format at up to 320 kbit/s or VBR is supported in the 2-channel recording mode. Officially the H2 supports SD flash memory cards, but some SDHC cards of up to 32GB capacity have been confirmed by Zoom to work. [5]
The H2 has a three-way gain input switch, with settings for low (useful for loud sounds, such as a live rock band), medium, and high (useful for speech, such as one or two people podcasting in a quiet room.)
Other features of the recorder are: [6]
LCD Display
Four internal microphones
2-Channel Stereo recording up to 24bit/96 kHz
4-Channel Stereo recording up to 24bit/48 kHz (Creates two sound files)
W-XY mic patterns with 4 mic capsules and signal processing allows Front 90° cardioid, Rear 120° cardioid and 360° polar patterns
Time Stamp and Track Marker functions in Broadcast WAV Format (BWF)

Auto Start function
Low-cut filter to remove wind noise
On-board chromatic Guitar/Bass tuner
1/8 External Mic In
1/8 Line Level In
Unlike the larger H4 Handy Recorder which succeeded it, the H2 does not include ports to accept XLR or 1/4-inch connectors, but has standard 1/8-inch (3.5mm) external microphone and line level inputs. The input jack for external stereo microphones supports plug-in power. [7] The H2 has built-in microphones, but allows external ones to be used if different characteristics are required.
Unlike the H4, the H2 makes no provision for multi-track recording, but its 360-degree polar sound recording can record in 4 channel audio, which can later be converted to 5.1 channel audio using computer software. [8]
The H2 and the H4, can be used as an audio interface to a computer. When connected to a host computer via USB, the H2 can act as a microphone, audio input (with microphone or line input) and output device with stereo line output. It can also be used as a USB file storage device.
Typical prices in the United States as of 2011 [update] were around US$350 for the H4n and around $200 for the H2 and H2n. [9]
The H2 began shipping on August 21, 2007. This was delayed from the original May 2007 shipping date due as an additional microphone was added; the original three-microphone Mid-Side design was lacking in some respects, and was abandoned in favor of the four-microphone W-X/Y design. The built-in high-fidelity electret condenser microphone capsules are arranged to allow stereo recording and have user-selectable parameters to allow for either a 90- or 120-degree pickup angle. The H2 can also be used to record a 360-degree soundfield.
MiniDisc (MD) is an erasable magneto-optical disc-based data storage format offering a capacity of 60, 74, and later, 80 minutes of digitized audio.
DV refers to a family of codecs and tape formats used for storing digital video, launched in 1995 by a consortium of video camera manufacturers led by Sony and Panasonic. In the late 1990s and early 2000s, DV was strongly associated with the transition from analog to digital desktop video production, and also with several enduring "prosumer" camera designs such as the Sony VX-1000. DV is sometimes referred to as MiniDV, which was the most popular tape format using a DV codec during this time.
A microphone, colloquially called a mic, is a transducer that converts sound into an electrical signal. Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, and radio and television broadcasting. They are also used in computers for recording voice, speech recognition, VoIP, and for other purposes such as ultrasonic sensors or knock sensors.
Nagra is a brand of portable audio recorders produced from 1951 in Switzerland. Beginning in 1997 a range of high-end equipment aimed at the audiophile community was introduced, and Nagra expanded the company's product lines into new markets.
Surround sound is a technique for enriching the fidelity and depth of sound reproduction by using multiple audio channels from speakers that surround the listener. Its first application was in movie theaters. Prior to surround sound, theater sound systems commonly had three screen channels of sound that played from three loudspeakers located in front of the audience. Surround sound adds one or more channels from loudspeakers to the side or behind the listener that are able to create the sensation of sound coming from any horizontal direction around the listener.
The DTX range consists of electronic drum kits and percussion controllers manufactured by the Yamaha Corporation. They currently cover levels from entry-level to pro-range. DTX kits use sampling for their sounds, meaning each kit has built-in digital recordings of real drums and cymbals. When the drum or cymbal pads are hit, the digital recordings are played back to replicate what is being played. On all kits, the sounds are editable – the pitch can be made higher or lower (tuned) and many other features. The higher the range of the DTX, the more functions there are editable.
Sound Blaster Audigy is a product line of sound cards from Creative Technology. The flagship model of the Audigy family used the EMU10K2 audio DSP, an improved version of the SB-Live's EMU10K1, while the value/SE editions were built with a less-expensive audio controller.
There are a number of well-developed microphone techniques used for recording musical, film, or voice sources or picking up sounds as part of sound reinforcement systems. The choice of technique depends on a number of factors, including:
Sony Corporation produces professional, consumer, and prosumer camcorders such as studio and broadcast, digital cinema cameras, camcorders, pan-tilt-zoom and remote cameras.
