This extension does not use VoiceView in any manner. It takes advantage of the support provided for Audible books on the kt4 and pw4 to play other media that sox supports either on your Kindle or streamed over the internet. It can be used to play mp3 audiobooks by placing them in the music folder.

Any plan of building an ability to resume an mp3 audiobook so I wouldn’t have to listen in one session ?

I can see the desire for this. I will have to check and see if sox can support this and then would have to determine how to accomplish it.

I assume you are stopping playback with the KUAL menu entry. If I can see a way for sox to support it, I guess I would need a separate "bookmark" menu entry and possibly a "resume" menu entry as well.

As I don't have a pw3 I can't test things directly here and have to rely on feedback from you and others. So I would in particular like you to test the ./play command and see if it works or not. I would also be interested in the output of which alsa on your pw3, as I think that might allow me to detect if it is available for me to use.

Try adding "-t alsa" to the end of that ./play command line after the file name and see if that works.

Dave

PS: if that doesn't work see if you can get aplay to play the file. If so I might be able to use it instead.

And it will only aplay a wav. It will aplay the mp3 binary (horribly sounding) as if it were a wav.

Ok. Try this one:

LD_LIBRARY_PATH=./library ./sox /mnt/us/music/Multitudes.mp3 -t wav - -- | aplay

Plays as a charm.

[root@kindle root]# cd /mnt/us/extensions/sox
[root@kindle sox]# LD_LIBRARY_PATH=./library ./sox /mnt/us/music/Multitudes.mp3

And Bob Dylan thanks you too:

[dhdurgee]

Great! I will work up a revised script for you to test and post it here. If I code this properly the new script will support both Kindles with gstreamer sound and alsa sound.

Dave

[dhdurgee]

Try this out, it works on my pw4.

Dave

[PoP]

With this small change works fine on the PW3:

#!/bin/sh
# script to play a local file on pw4

# add required library

export LD_LIBRARY_PATH=/mnt/us/extensions/sox/library:$LD_LIBRARY_PATH

# get soxi data from file to be played

/mnt/us/extensions/sox/soxi "$1" >/var/tmp/soxidata.txt

# now to parse necessary information

Chan=$(awk -F: '/Channels/ {gsub(" ","");print $2}' /var/tmp/soxidata.txt)

Wide=$(awk -F: '/Precision/ {gsub(" ","");gsub("-bit","");print $2}' /var/tmp/soxidata.txt)

Rate=$(awk -F: '/Sample Rate/ {gsub(" ","");print $2}' /var/tmp/soxidata.txt)

rm /var/tmp/soxidata.txt

# now determine how to play it

Ugh. Missed that change when I copy/pasted the sox part. Glad you were able to spot it. Now that the concept is proven I can adapt the existing scripts and release with pw3 support as well. Thank you for your assistance in testing this out.

Dave

[dhdurgee]

I have tweaked the script a bit more giving priority to ALSA if available, which required dealing with the case of ALSA being present but not usable. I have attached the modified script and would appreciate confirmation that I didn't break ALSA support for you.

Dave

[PoP]

Nothing broken, I can still play Dylan

I am releasing a new version with pw3 support. I am updating first post with the new zip.
