    Alternatives to Raven or Audacity for iPad?

    No. But I don’t see freq/time spectrograms? The challenge is that as I learn bird sounds, I need to see spectrogram which is like a visual fingerprint. Even editing- e.g. snipping a certain bird out of a longer recording - is tedious if you can’t visually see its vocalizations. If you use...

    Thanks… but looks like no-go on iOS :-(

    Alternatives to Raven or Audacity for iPad?

    Niels, I’m far from pro but so far I’ve learned: Noise reduction often leads to warbling, weird sounding effects in resulting audio. Must be used very sparingly… Noise reduction is a two step process. First you select a section with noise you want to remove (just the noise so typically a...

    Alternatives to Raven or Audacity for iPad?

    Of course you know this is all at least partially your fault. Seeing your artwork made me want an iPad to sketch with ;-) But the lack of an audacity-like-app is killing it for me. I don't expect all the fancy features, but some basic editing and spectrogram view are must-haves. For me...

    Alternatives to Raven or Audacity for iPad?

    I have owned iPads in past but don't currently. Thus my questions... The little XPS13 2-in-1's look nice but the price starts going up. Advantage is it's a 'real' PC where as you correctly point out, I can transfer all my software. First world problems, I know :-P

    Alternatives to Raven or Audacity for iPad?

    The assumption is I don't always have 'cloud' (internet connection). The need is for travel mostly. At home I have a PC workstation. I'm birding and I use Merlin or other iOS recording app on phone. Or I use my little Tascam recorder. Typically I get home, move files via SD card onto...

    Alternatives to Raven or Audacity for iPad?

    Yes, yes, and yes... except for the bit about iPad and serious work ;-) The iPad - in terms of stylus, battery life, form-factor, etc. - makes a fabulous travel data-device. As someone mentioned in my other iPad thread, it also is great for kindle or PDF guides, books etc., photo editing...

    Alternatives to Raven or Audacity for iPad?

    As far as I can tell, all the reviewed apps show volume-over-time as opposed to frequency-over-time. The latter is what you want to see in order to ID bird sounds. Here's a Worm-eating Warbler using Audacity (free). Cornell makes Raven Lite avail (also free). In blue is volume (dB on vertical...

    Alternatives to Raven or Audacity for iPad?

    Has anyone found a way to edit/view bird audio - which includes good spectrogram viewing functionality - that runs on iOS (specifically iPad)?
