Free music platforms can be messy – hard to find the good stuff – but worth searching. Another category of platforms offer free mp3 quality and charge for HQ versions – these sites are better organized.
Freesound.org offers a huge archive of free sounds (registration for free)
opsound.org is dedicated to open source culture offering free sound & music
Netlables by archive.org. You can search by tags and keywords, most audio seems to limited to 30 seconds free sample.
archive.org millions of books, films, music and more on this huge open source page
digccmixter.org great archive, searchable by tags, but navigation very simple & basic
Bargus.org small archive
CChound.com – under repair
Stampede.it cool page, but just a few free audio files besides commercial offers
Jamendo mp3 for free, HQ for payment
Icons8 mp3 for free, 44.100 Hz version for 2o$ monthly subscription
More CC music links here on CreativeCommons.org. Some of the platforms like Jamendo have free and commercial offers, so always keep your eyes open.
Royalty free music: what to learn by commercial sites
There are constantly new music sites for filmmakers popping up, offering royalty free music for a flatrate price (monthly subscription price to access huge and well organized libraries for unlimited use), the most famous are Soundstripe and Artlist. Since you have to buy a plan for a year minimum at both sites, these offers are not cheap, but it helps to learn more about how navigation of a well organized library looks like and what to expect from better pages for free music (like cchound and Icons8).
epidemic sound recommended by my friends, I didn’t try it yet. It has a free one month trial, monthly plans starting from 15 $ per month for social media use, but expensive for companies (149 $ per month)
Musicbed, starts with 9 $ a month for social media use, used by travel filmmakers like Bryn North in Mongolia
