Did you know that the smallest voice recorder in the world, entered into the Guinness Book of Records three times for its miniature size, is made in Russia? It is produced by the Zelenograd company "β, the activities and products of which, for some reason, have not yet been covered in any way on HabrΓ©. But we are talking about a company that independently develops and manufactures world-class products in Russia. Miniature digital voice recorders have long been her calling card among professionals, and this story is about them.
About
The company with the simple name "Telesystems" was founded in Zelenograd by two enthusiasts in 1991 as a private research and production enterprise, the main activity of which was the development and manufacture of electronic equipment for communications. In 1992, Telesystems developed and manufactured the first AON in Russia, which became the basis of the company's business in the 90s. Since then, the company's product range has expanded significantly. Now one of the company's calling cards has become a series of miniature professional voice recorders Edic - for the past 6 years Telesystems has been holding the title of manufacturer of the smallest voice recorders in the world.
Success story
Already in 2004, the Edic Mini A2M voice recorder as the smallest voice recorder in the world:
With an extremely small size (43 x 36 x 3,2 mm) and a weight of only 8 grams, the Edic-mini A2M recorder has a recording time of up to 600 hours, while the battery life is 350 hours. Such a recorder costs about $190.
In 2007, she got into the book of records which, by the way, is still in production today.
with quite decent memory of 8 GB, its dimensions are 8x15x40 mm, and the weight is a little less than 6 grams:
In 2009, the current ultra-lightweight champion entered the market - EDIC-mini Tiny A31, the size of a paper clip:
Its built-in memory can reach 1200 hours, the sensitivity of the microphone is up to 9 meters, the voice recorder can work up to 25 hours from a fully charged battery.
However, miniature size is not an end in itself for telesystem recorders. This is a professional product with high quality recording, acoustic sensitivity up to 7-9 meters, automatically adjustable recording volume, powerful memory and password protection.
Another feature of Edic recorders, which expands the scope of their application, is digital tags, a kind of audio signature that allows you to establish the authenticity and integrity of the recording made on it, as well as the absence of its later editing. Thanks to this, a recording made, for example, using the Edic-mini Tiny B22 voice recorder, can be presented as evidence in court. How and why such a feature can be useful in our country, I think, there is no need to explain.
You don't have to be a sound recording pro to experience the possibilities of telesystem technology - a simple test at home is enough. For example, you can at night from a distance of 50 meters.
PS
Although voice recorders have become the most stellar product of Telesystems, the company's business is not limited to them. Zelenograd produces equipment for telephony, security systems, decorative lamps, invests in startups, supports crazy projects in various areas - electric transport, solar energy, mobile homes, light aircraft and hang-gliders, and much more, which I will talk about in future articles.
P.P.S
It is symbolic, by the way, that the company is from Zelenograd. In recent years, without any instructions from above and accompanied by the constant drank of budget initiatives, Zelenograd has really turned into an "innovation city", a city that really has a chance to become a real Russian Silicon Valley.
