It has taken me a while to get this one together. I am still experimenting with recording on the hoof. This time I decided to record a series of short clips in Voice Memos. the intention was to string them together quickly with Ferrite. I found that a bit footery on the phone and ran into the three track for free limit.
Returned to the problem on the iPad and Hokusai. Only took a few minutes. Both ferrite and Hokusai are made by the same developer! I think I might read Difference: Between Hokusai Audio Editor and Ferrite Recording Studio — Wooji Juice I need to get a bit more practice with these apps.
