## Motivation

||||||
|
|
||||||
![Pixabay Bild: guitar-946701_640.jpg](https://pixabay.com/de/images/download/guitar-946701_640.jpg)
|
|
||||||
Mit meinem Hauptinstrument – der (E-)Gitarre – mobil(er) sein:
|
|
||||||
- wenig(er) schleppen, aber trotzdem volle Flexibilität
|
|
||||||
- unterwegs wie gewohnt Musik machen und Ideen festhalten können
|
|
||||||
|
|
||||||

|
|
||||||
Smartphone mit [DivestOS](https://divestos.org/) (Android)
|
|
||||||
|
|
||||||
## Software
|
|
||||||
|
|
||||||
### Arch Linux
|
|
||||||
|
|
||||||
- Ardour
|
|
||||||
- Guitarix
|
|
||||||
- Pipewire
|
|
||||||
- etc.
|
|
||||||
|
|
||||||
### Smartphone (Android):
|
|
||||||
|
|
||||||
#### Anforderungen
|
|
||||||
|
|
||||||
- kostenlos
|
|
||||||
- keine Tracker (geprüft mit [εxodus](https://reports.exodus-privacy.eu.org/de/) und [ClassyShark3xodus](https://forum.xda-developers.com/android/software-hacking/dexdump-xodus-trackers-apk-static-t3833391) von F-Droid)
|
|
||||||
- keine Werbung
|
|
||||||
- hängt nicht von GSF ab
|
|
||||||
|
|
||||||
#### Auswahl
|
|
||||||
|
|
||||||
keine Apps in [F-Droid](https://f-droid.org) gefunden **:(**
|
|
||||||
|
|
||||||
![Google Play Grafik: Guitar-Effects Alterative](https://play-lh.googleusercontent.com/uyeCzEbF_l2i8riHTxGoNp25vp4Ey9l4iq04lA2Q4oC-3J2GgbmdhkEGaeiGSJ66CQ=w240-h480)
|
|
||||||
[Guitar-Effects Alternative](https://play.google.com/store/apps/details?id=com.laruta.guitar_effectsalt):
|
|
||||||
- nicht *Guitar Effects*, da dieses unnötigte [Berechtigungen](https://reports.exodus-privacy.eu.org/de/reports/com.xtraid.guitareffects/latest/#permissions) (Internet) verlangt!
|
|
||||||
- hat nicht funktioniert (keine automatische Erkennung und keine Sound Interface Auswahl möglich)
|
|
||||||
|
|
||||||
![Google Play Grafik: Delay Effects](https://play-lh.googleusercontent.com/OdRbI5_8PetzlGnxnvza-kliu7oIigFJEfQCOfFdMd0TMwgZ8UeR0xSojOWr1w8mCkK0=w240-h480)
|
|
||||||
[Google Play Grafik: Delay Effects](https://play.google.com/store/apps/details?id=com.delayeffects):
|
|
||||||
- hat im Test funktioniert, aber
|
|
||||||
- hohe Laten (vmtl. `512` Frames bei `2` oder `3` *Periods*)
|
|
||||||
|
|
||||||
![Google Play Grafik: Handy Recorder](https://play-lh.googleusercontent.com/RpdPBs6FzUfLkHHzK_KOvehjvJRLBOnn_gRGNZE0rVTVYjg6itUnzAne62-IEuIQYLtP=w240-h480)
|
|
||||||
[Handy Recorder](https://play.google.com/store/apps/details?id=jp.co.zoom.handyrecorder):
|
|
||||||
- vom Hersteller des Audio Interfaces (ZOOM)
|
|
||||||
- nur für Aufnahmen geeignet (hohe Latenz)
|
|
||||||
|
|
||||||
## Fazit
|
|
||||||
|
|
||||||
![Pixabay Bild: railroad-line-3121544_640.jpg](https://pixabay.com/de/images/download/railroad-line-3121544_640.jpg)
|
|
||||||
- einen Schritt näher an "jederzeit und überall" Musik machen können
|
|
||||||
- manchmal schleppe ich trotzdem ohne Zeit zum Spielen zu finden, aber
|
|
||||||
- es lohnt sich dennoch mich bei Inspiration (wortlos) ausdrücken zu können
