Until now, we have supported you in your purchase decisions with our tests for single devices. However, they vaguely hint at the differences in quality of recording devices. With our old tests, a direct comparison could hardly be made, because each device was tested under different circumstances. Therefore, we decided to test all digital recorders at the same time and under similar circumstances, so that you can easily compare them. Additionally, we prepared some sound samples for you. We hope that you enjoy reading our test and listening to the sound samples.

f5 is a program which supports the transcription progress, the progress of manually writing down interview situations from video or audio files. Your work is alleviated by f5, because it slows down the playback speed without changing the pitch. You can control the playback with a footswitch or shortcuts. Whenever you pause the playback, f5 automatically rewinds it. An innovative function of f5 is that it synchronises your text with your current media file by adding a cue point to every paragraph. This allows you to directly jump to the passage you want to replay.

With our footswitch model „office“ you can easily operate the playback of your audio and video files with your feet while your hands can remain on the keyboard. The footswitch is compatible with Windows, Mac and Linux systems. It can accelerate your typing process up to 30%.

f4 supports your transcription process, meaning your personal typing of video or audio recordings from interview situations. Applications like Windows Media Player or iTunes do not qualify for this kind of work. They lack essential features that simplify the transcription process. Automatic voice recognition software will cease operating if there is more than one voice involved (which is usually the case during an interview).

Converting existing audio data into .mp3 format is fairly simple with most programs. We opted for SWITCH as it is free software which is particularly easy to use and which can read and convert most data formats. It also has a unique ability to convert the digital voice recorder format .dss and many other audio formats into .mp3 without hassle. The program is also remarkably small.

No installation is necessary, simply download it and double-click to start.

A test report by Dr. Thorsten Dresing and Thorsten Pehl (Sept. 13th, 2007)

The new ZOOM H2 has been announced for a long time and eagerly awaited since then. For an MSRP of 236 Euros, it was expected to unify many functions in a single, palm-sized device and to be an MP3/Wave recorder extremely easy to handle. But would it finally satisfy all the high expectations? The device arrived at our place on September 13th, 2007, and our test report presents the Zoom H2 in detail for you.

Telephone interviews are a popular and relatively inexpensive way of gathering data. The technology used for such interviews must be capable of making acceptable quality recordings of both interviewer and interviewee. However, such recordings always have an inferior sound quality to recordings of face-to-face interviews or recordings made using a voice recorder. Our tests have revealed that two feasable options are available for making recordings over the telephone:
