Auv3 effect with reverse delay or looong delays?
I've been out of the iOS music game for a few years now, about the time that Auv3 apps started emerging. My old go to delay was AUFX: Dub, which was great because it had delays up to 5 seconds, which I used to for frippertronics style playing and feedback loops. Sadly, it has not been updated to Au yet, and I don't have many other delay options at this point.
I'm looking for 2 kinds of delays (or apps with similar functionality):
1) a delay or buffer effect with durations longer than 3 seconds.
2) a delay or buffer effect that can reverse incoming audio.
Any suggestions guys? My research has found plenty of Auv3 fx, but none with those super long delays, or reversing capabilities.

FS Reverser Delay and Eventide BlackHole would be worth checking into
The yaleD Reverse Delay AUv3 does exactly what you want for #2. You can set it up to have a max delay buffer of 25 seconds. It’s a reversing only delay though.
That yaled one I think maybe?
Try yaled by the guy who made thumbjam. I think it goes up to twenty seconds, and it was super cheap the last time I checked. Another option is AD Enso. I also think there’s a frippertronics style demo floating around this forum by someone (sorry I’m terrible with names 😅) using kosmonaut and aum.
Hope this helps, good luck
YaleD for reverse and Kosmonaut is just a great delay
I knew something as simple as this had to exist! That was exactly what I was looking for, just installed it and will give it a play in a minute!
Tap Delay by Virsyn. Nice for long delays. I use it for Frippertronics-type things.

Tap Delay looks great, and I love Virsyn. Any idea what the longest delay time available is?
Great, let me know if you have any questions about what it can (or should) do.... you can sync it, or manually trigger it... it's a bit deeper than it looks.

I think you're referring to this one:

+1 for Enso - you can set up a long loop (with overdubbing if you wish) which can play forwards or backwards, so more of a tape delay style, but I think it will do what you want.
Certainly will do.
My intention with the app is to aid in elaborate feedback loops using the buffers in ipulsaret. yaleD will allow me to reverse certain points in the feedback chain, and further along in the chain allow me to reverse it back to its forward playing state.
I've already found that putting two instances in series, will produce an expected forward delay, which is great. One question though: a single instance doesn't do just forward delay, right? I did see that it does alternating delay option though.
10 seconds which is plenty for me. There are others that have longer delays but I’m happy with the results and immediacy of Tap. YMMV
Great, that's plenty for me as well. If we needed any longer we could always put two instances in series anyway.
Thanks for the info! I'll pick this one up as well
Cool hack to get a forward delay out of it
You are correct in that there is no built-in forward only delay... it does have the alternating direction feedback option though.

So I have been experiencing some unexpected behavior from yaleD.
In my video you’ll see that I’ve maxed delay time to 5 seconds, I play a series of 3 notes and 5 seconds later they repeat in reverse - fantastic. But then, I get some weird early delays / bleed through? The first one you’ll notice happens at 11 seconds in when I play D4. This almost always occurs. I’m not sure if I’m hitting some dsp limit or something, but I’m floating about 18-20% on my cpu.
It seems like the the early sounding delay is somehow getting caught in the tail of the previous delay cycle. Strange.

It seems to be 10 seconds.
Yep, 10secs. Here are the settings for a single 10sec repeat.

I’ve fed about 3 notes through this with feedback way up and the Saturation, Tape Hiss etc. turned up a bit and had an ever changing pallet of sound come back for an hour. I could’ve continued but I had to go out. That was in the days when I could go out... 😭
If you play something just before the reverse boundary you will hear it immediately, and I suspect that is what is happening here. If you turn on the "tap for visual" you can see where in the cycle the delay is so you could see if you just got unlucky with the timing, causing this behavior.
TapDelay ‘s biggest party piece, in my opinion, is the really nice parametric eq you can play with in the feedback path... For me that’s where a lot of the majik happens... especially if you’re using a midi controller.
In the world of hardware, I’ve been using Akai’s Headrush for more than a decade. In my quest for doing as much as possible in my iPad, I’ve been looking for a delay app having > 20 seconds delay time for Frippertronics. This might not be your cup of tea, but since ‘I’ve not found anything to my liking, I used mirack to cobble together what I want. The input goes to a mixer and feeds a 10 second delay. This first delay feeds a second 10 second delay. The second delay’s output goes to both the output and the mixer for regeneration. This is rev 1. I plan on developing this further. I hope this helps.
On iOS “yaleD” is the best option, in my opinion. There is also an inverse reverb in IK Multimedia’s “MixBox CS” and if you want a tape-style loop reverser, there is always “Gauss”. And the “IMPULSation” reverb app has some pretty good reverse reverb impulse responses built in.
And the “Mela 3” synth has some outrageous reverse-style effects when you apply Mela 3 to your track as an AU effect. Completely bonkers.
And my preferred method, you can simply play the GeoShred app, which has a Frippertronics setting which achieves this exact effect without all of the complications.
Wow you may have finally sold me on IMPULSation. I have a Thafknar and love it for IRs but never bought GMs offering. Still waiting on another good sale for Mixbox though.
Agreed about Mela 3, it’s a fantastic app. Geoshred too.
Never realized this about tap delay. Might have to pick it up now. Is it the best way to get the whole Frippertronics thing? I know Enso can do it but it can be buggy at times.
I believe Frippertronics was typically much less than 10 seconds delay. From some article on the internet (but I’ve seen this elsewhere too):
“The record head on the first Revox tape deck was routed to the playback head on the second deck, which then ran back to the first deck.
The result of this constant recording and playing was a delay loop, the length of which (usually 3-6 seconds), depended on the distance between the tape decks.”
There is a good chance that impulsation’s reverse reverbs are nothing more than reverb IRs that have been reversed. You can open any reverb IR in an audio editor that can reverse a file (which is probably most of them) reverse it and save it and load it into THAFKNAR.
If you want really long delays, Gauss goes up to 45 seconds. You use the loop decay setting to get it to fade with each repeat.
IMPULSation is, in fact, an IR app. And it's a very good one. I love it. I previously tried Thafknar and found it poorly designed and unpleasant to work with.
I know that impulsation is an IR app. I was replying to someone who likes THAFKNAR to let them know they don’t need an additional app to do reverse reverb IRs.
