I'm pretty proud of this `getvoicerecorder.sh` script that I use to pull .wav voice recordings from my phone, convert them to .mp3, and delete the originals from the phone memory (assuming you have Android Debug Bridge adb tool installed):

    #!/bin/bash

    # On the computer
    MYHOME=$HOME
    MYDESKTOP=$HOME/Desktop
    DEST_DIR="Voice Recordings `date "+%Y-%m-%d"`"

    # On the phone
    VOICE_RECORDER_SOURCE_DIR="/sdcard/EasyVoiceRecorder"


    # 1. make the dest dir and cd into it
    cd $MYDESKTOP
    mkdir "$DEST_DIR"
    cd "$DEST_DIR"
    # list files that will be downloaded:
    echo "The following files will be adb-pulled, converted, and saved to $DEST_DIR"
    adb shell ls "$VOICE_RECORDER_SOURCE_DIR"

    # 2. PULL
    adb shell "cd $VOICE_RECORDER_SOURCE_DIR; tar -cf allwavs.tar *wav"
    adb pull $VOICE_RECORDER_SOURCE_DIR/allwavs.tar allwavs.tar

    # 3. PROCESS
    tar -xf allwavs.tar
    for f in *.wav; do
      echo "Converting $f to mp3...";
      ffmpeg -hide_banner -loglevel panic    -i "$f" "${f%.wav}.mp3";
    done
    # set timestamp to match what was on the original .wav files
    for f in *.wav; do
      gtouch -d "$(date -R -r "$f")" "${f%.wav}.mp3";
    done

    # 4. cleanup
    rm *wav
    adb shell "rm $VOICE_RECORDER_SOURCE_DIR/allwavs.tar"
    rm allwavs.tar
    echo "Deleting all .wav files from phone..."
    adb shell "rm $VOICE_RECORDER_SOURCE_DIR/*wav"

It's part of a general authoring workflow: whenever I want to write something in a conversational tone (as opposed to dry/technical/academic tone), I go for a walk-and-talk, then transcribe the dictated text + edit. Works really well for intros and conclusions in particular, and blog posts.
