7 Free Audio Effects That Should Be In Your Library Right Now


Published by The Supreme Team on July 10, 2020



free audio effects

There are tons of free plugins out there. In fact, there are so many that it can be downright overwhelming to find the true gems while looking through hundreds of options.

That being said, some free audio effects are so invaluable that they’ll make great additions to any SoundCloud producer’s library. In this guide, I’ve listed some of my favorites that no paid software can replace for me. I use them all the time- and so should you!

1) iZotope Ozone Imager

iZotope’s Ozone Imager is the best stereo widening tool I’ve ever used, hands down. Not only do I use it on my mastering chain, but I also often apply it to my synth pads and background vocal layers as well. I even use it to disperse ambient reverb effects more evenly sometimes. It glues my mix together like no other, and it’s incredibly easy to use.


2) iZotope Vinyl

Another free offering from iZotope, this vinyl emulation plugin will add that warm, lo-fi touch to your lifeless MIDI instruments. I use this one mostly on synths, but it works wonders on virtual strings, woodwinds and brass instruments as well. If I’m looking to change the tone of an instrument because it’s not sitting well in my mix or it sounds way too pristine, I give iZotope Vinyl’s “Year” options a try, which help highlight certain frequencies while concealing others. I also enjoy playing around with the “Warp Model” and “Warp Depth” parameters for sound design purposes. All in all, Vinyl may be advertised as an audio-aging product, but it really does go beyond that.



3) Cableguys PanCake 2

Cableguys’ free panning modulation plugin is a huge time saver. If you want Soundcloud promotion real a specific repeating panning pattern that you yourself design without automating the pan knob on your channel, look no further. This plugin can be tempo-synced to your DAW, it allows you to draw the exact shape of the panning modulation you want Soundcloud promotion real and even choose how frequently it repeats. I love using this one on just about anything, but it works especially well on beats. Running hand drums and shakers through this thing can inject a multi-dimensional and immersive feel into your groove. Just make sure you insert it on a stereo channel, since it doesn’t work on mono.

4) Valhalla Freq Echo


I’m a huge fan of Valhalla’s reverb and delay plugins in general. No one produces frequency-shifting time based effects like the way they do, and the Freq Echo is no exception to this rule. It offers a great range: you can go as subtle or psychedelic as you want Soundcloud promotion real with it. It comes with a wide delay note division sync selection and gives you the option to EQ echos as well. But the most exciting parameter is the “Shift” knob, which helps you shift the frequencies of the echos, adding a lot of depth to any instrument that feels a little too one-note or robotic. If I’m working with a hi hat and I just know I need to add some excitement and variation to it, Valhalla Freq Echo is my first stop.

In the past two months, Valhalla has added two more free effects to their collection: Valhalla Supermassive and Valhalla Space Modulator. Both, unsurprisingly, sound incredible and are especially great for creating massive soundscapes.

5) Tritik Krush

Tritik’s bit crusher is so fun to use, not only because it’s essentially a multi-effects plugin, but also because it comes with a really exciting preset selection to help you get started. If you’re into glitchy and grainy sounds, this plugin will be your new best friend. Since it’s an amplitude-based effect, it will manipulate the volume of your signal when you use it, just like most distortion and bit crusher plugins do. In other words, it might take a minute to get it to sound right in your mix. However, its versatility will surprise you once you get used to it. Most recently, I used it on a return channel right before a long plate reverb to add a sparkly touch to my vocal mix. Never thought it would work so well- but it did!

6) Soundhack Bubbler

This granular delay plugin from Soundhack’s freeware bundle has a very specific sound. The glassy, almost crystal-like, fast moving pitch shifted echoes that it produces may not be everyone’s cup of tea, but those who are into sound design will be impressed by the results. Like Tritik’s bit crusher, Soundhack’s Bubbler, too, sounds really good with a ton of reverb and it can be a great fit for any electronic production from ambient to EDM. Its unique settings might look a little confusing at first, but it’s the kind of software you just dive into and learn by doing. I often use the “Grain Size”, “Octave” and “Octave Variation” knobs more than anything else.


7) Soundhack Pitch Delay

Bubbler’s cousin Pitch Delay is another favorite of mine from Soundhack’s freeware bundle. It looks simpler, but it can create dramatically altered sounds. While controlling the pitch via ratios might be difficult to work with in a really musical production, the “Octave” and “Cents” parameters will produce echoes that are easier to fit into the key of your song. Like the Bubbler, the Pitch Delay requires you to just dive in and explore. My advice: try working with a short, one-note sample at first to accurately assess what these Soundhack plugins can do.

  • This field is for validation purposes and should be left unchanged.

    2. Our Influencers have between 10k – 500k followers each.
    3. Influencers repost your song to their followers.

  • What are you going to do for me?
    We give your release a boost by getting it in front of a real audience. We provide you with a "first wave" of engagement that you may not be able to get otherwise. What happens next is up to you and your music.
  • How long do reposts last?
    Reposts stay active for 48 hours. After the first 48 hours, your reposts are too far down the stream to be noticed. Removing them keeps an influencer's channel from being over-used and outdated.
  • Will I go VIRAL from one organic soundcloud promotion?
    The truth is, probably not. Unless you have the next “The Box” in your pocket, you are probably not going to blow up from one promotion. We are not going to bullshit our clients and make false promises. Think “Brand Building” not “Overnight Sensation.”
  • Will I get noticed by labels?
    The best way to get noticed is to keep your brand in front of an audience while producing top quality material. Labels want real artists who already have a brand together, who self-promote and have a good presence on Soundcloud and Spotify. Please, don’t expect to send out some reposts and get signed. This is the most competitive business in the world.
  • Can I have the links to your influencer channels? 
    No. It took us many years to build our network.
  • How many is a million?
    The number represents the total amount of followers your song is shared with. It doesn’t mean that your track will be reposted by a million influencers.
  • Can I split an order between multiple songs?
    We require a minimum of 1 million reposts per song when splitting an order. The minimum order you can split between two songs is 2 million reposts.
  • Can I change the link to my song?
    Unfortunately, no. The organic Soundcloud promotion can't be forwarded. It is okay to change the title or other meta-data, just not anything that affects the link.
  • What if no one likes my music? 
    If we can't get anyone to repost your track, we will refund all of your money.
  • Are the organic SoundCloud followers real people who will become fans?
    They are fully organic, real, living people who have downloaded other music from our fangates and given the option to follow you. Once they are following you they will receive your music in their streams and it's up to you if you connect with them and build your community. This is how to turn them into "Superfans."
  • Will they immediately like my music?
    New followers are not automatic "fans" and will probably not engage your tracks right away. You have to engage them by streaming good music, following them back, comment on their stuff, and chatting with them.  Build your community.
  • How Long does it take to gain 1000?
    Once the campaign has started, you can expect 1 week per-1000.
  • How can I track the progress of a campaign?
    Watch your organic Soundcloud followers grow on the Pulse app or in Notifications on the website.
  • Can I change the link to my profile after I order?
    No. Unfortunately, the promotions can't be forwarded. It is okay to change the title or other meta-data, just not anything that affects the link.
