What we do

We are field recordists. We hunt sound.

But that is not all. Since we are also sound recordists and sound designers, we know the workflow needed for a sound effect: from pre to post, from research to wrap, from editing to sharing. We record, edit and master. Our sound collection will never stop growing.

At GainWalkers we produce high-quality sound effects collections for creative professionals in video game, film, television and other media. GainWalkers is owned and run by Pablo Valverde and Andrei Leskovski, two Sound Recordists & Sound Editors based in London (United Kingdom) and Madrid (Spain).
All our products are delivered in ZIP files, which include WAV audio files with embedded metadata, PDF and XLS spreadsheets, and text files. Downloadable links to the products are delivered to you immediately after the payment.

Many of our collections are in Ambisonics, which is a kind of format that represents a full-sphere surround sound, mainly used for Virtual Reality and 360º videos. Please read our Ambisonics guide.

Are you in need of any kind of sound effect? Let us know and we will record it. Whether it is for a game or a film, we do know the differences and the necessities for each one. We have the experience. We hunt sounds.
