The library “Montreal 365” is the result of a long 5 years endeavour. These sounds were recorded through 5 years of field recording around the city of Montreal, Canada. It captures the wide variety of the urban facets and comprises all 4 seasons through which the soundscape is largely modified. The library has 2 main types of captures: interior and exterior. Montreal is a large North-American cosmopolitan city with a European flavour. Many different ethnicities reside there. The main language is French but English is also omnipresent. The highly varied seasons mark the landscape and influence the moods and energy of the city. These were thoroughly recorded in high definition ORTF and mastered with precision. Most of these ambiences are loopable. They thus are easily useable in any production.
