Play it slowly

Hi, I'm very interested in playitslowly, but it don't work on my archlinux.

gst.ElementNotFoundError: pitch

I have python-2.6, pygtk 2.13, and pygst 0.10.13 on my system. Any hint ?

great work !

Comment by Fernando Henrique — 1/4/09 11:56 PM | # - re

Hi Fernando,
Archlinux doesn't have the gstreamer pitch element. You can easily compile that yourself:
pacman -S soundtouch
cd /tmp
wget gstreamer.freedesktop.org/src/gst-plugins-bad/gst-plugins-bad-0.10.9.tar.gz
tar xzf gst-plugins-bad-0.10.9.tar.gz
./configure --prefix=/usr
cd ext/soundtouch
make && make install
test with:
gst-inspect-0.10
I hope that helps!

Nice, works on my Ubuntu once I installed the GST plugins. Didn't know they can do that. I have some suggestions:

Make a deb package, provide an uninstall script, or at least make it such that people can 'try before you install'.

Doesn't it make more sense to adjust pitch by semitones than by decimals?

Comment by Sam — 1/5/09 2:14 PM | # - re

Hi Sam,
"try before you install" is possible, just extract the archive and execute ./bin/playitslowly. I already asked the getdeb.net guys to create a .deb package.
Regarding the pitch makes perfect sense, I was just to lazy to do that so far.
Cheers,
Jonas

Hello, I am trying to run playitslowly on Ubuntu Hardy, and I get no sound and this on the terminal:

-----------------------------------
Traceback (most recent call last):
File "/usr/lib/python2.5/site-packages/playitslowly/playitslowly.py", line 246, in updateposition position, fmt = self.pipeline.playbin.queryposition(TIME_FORMAT, None)
gst.QueryError: query failed
-----------------------------------

Can You help me how to solve this? I guess I have installed everything I need..

Thanks

Hi ElPraga,
That should work in the new version.
Can you try this please?

Comment by Jonas Wagner — 1/8/09 3:49 PM | # - re

Hello Jonas! Thanks a lot!! The version 1.1 is working fine. I have one feature request though. It would be quite useful, if one could invoke playitslowly via "playitslowly file.mp3" (at least I did not find a way how to do it :-) ) It is not a big deal, but it would be nice.

Tomas

Comment by ElPraga — 1/9/09 12:05 AM | # - re

Hi Tomas,
I'll add that feature this evening.

Hi, I can use "playit" by learning languages, but I wasn't successfull with the compilation. I am a current user. I use Mandriva from 2002, so for me could be rpm packages the solution. I Hope, it will be made in time.

Comment by chris — 1/25/09 3:11 AM | # - re

Hi Jonas. First of all great little program. Thanks! I post this just if someone else needs to output on a different soundcard than the default one. You can do it by running:

playitslowly --sink="alsalink device=hw:1"

the part in the brackets was the hard part to find...

Btw, I understand that the start/stop sliders are limited to 0.1sec increments. It would be nice to be able to create perfect loops hence requiring a finer resolution. An idea would be to use keyboard shortcuts to precisely set start and stop positions. What do you think?

Comment by Claudio — 3/23/09 8:56 AM | # - re

Hi Claudio,
it might make sense to add a textbox to the left. Although the the timing of the stop slider is not that accurate anyway (right now). By the way it is playitslowly --sink="alsasink device=hw:1"
Cheers,
Jonas

Comment by Jonas Wagner — 3/24/09 11:54 AM | # - re

Hi Jonas.

Very nice little program, thank you.

I'd like to make two suggestions:

The install script scans for dependencies, so that you find out what you're missing while in install mental mode, not while running it, and:

It would be really helpful if the "position" was in h:m:s, in case I've marked times in an interview, or are switching between different programs.

Cheers.

Hi Dubito,

Comment by Jonas Wagner — 5/8/09 12:17 PM | # - re

Hi, Jonas,

Thanks for your Program, I use it quiet often - I play guitar too and I like it especially because the Soundtouch library doesn't change the sound and volume that much when slowing down - compared to the plugin for audacious.

Unfortunately after my last update on my Ubuntu 9.04 your program didn't start anymore complaining it can't load your mygtk library ( on playitslowly.py at line 43).
I helped myself by changing the line from:
from playitslowly import mygt
to
import mygtk
Now it runs perfect again.
Maybe that helps anybody having the same problems as I did.

Cheers,
Christian

Comment by Jonas Wagner — 5/10/09 10:31 PM | # - re

I've spend quite some time looking for a suitable player for transcription of the interviews and was glad to discover playitslowly. I would be happy to start using it right now, however I see at least two essential features missing in the latest version.

1) rewind/forward action. It would be nice to have even two implementations of these with different increments (say 1 and 5 sec).

2) global controls. These can be implemented either through some kind of playitslowly-remote with command line switches (--play-pause, --rw1sec, --fw1sec, --slower --faster), or through dbus interface. However, from my experience the latter is so slow that it will be almost useless for this purpose.

with those features implemented playitslowly would be an ideal tool for my task.

While searching I also found another project, which is supposed to serve the same purpose as yours. It is nicely made, even thought not very stable on my system. I'm sorry to see that it looks like abandoned since 2006, but perhaps you can borrow some ideas from there.

Anyhow, thanks for the good job and would be nice to see this project developing further.

This program works well on sound, but not on video. That is, I can watch a video while slowing down the soundtrack, but the video will play at normal speed. I'm running it in Ubuntu Ibex.

Awhh, that looks like I broke support for python2.5 by using a class decorator in the metronome, that's not even used right now. I've fixed it in 1.2.1 earlier today :)
Can you please confirm me that it works now?

Hi,

I heard about this cool tool from my friend. I would like to give it a try but cannot get it to work under gentoo. I'm hopeless. Maybe you could tell where the problem can be. Here is a thread on forums.gentoo.org: forums.gentoo.org/viewtopic-p-5939010.html#5939010

Comment by luboss — 8/21/09 12:29 PM | # - re

Thank you Jonas for the solution. Playitslowly finally works (btw except manual soundtouch compilating I had to download gst-plugins-good and gst-plugins-ffmpeg). The tempo fine-tuner works awesome but I had problems with playback. I cannot even pause or rewind (the button doesn't work at all). I tried gst-inspect-0.10 playback and I can see that it's available (gst-plugins-base).

Comment by luboss — 8/21/09 6:14 PM | # - re

Btw, I would like to ask if it is able to tune the pitch more finer than just whole tones. I mean now only I can is change the pitch from 0 to +1 +2 but cannot do something like +0.25 which would be very helpful. For example in case that guitar tunning is slightly different than the song's one (for example 440 vs. 460). If not I would like to suggest it for the next release.

Comment by luboss — 8/21/09 6:16 PM | # - re

Actually the pitch is currently changed in semitones, not whole tones. I'll think about a solution to your problem when I create the next version.

Jonas

Comment by Ronen — 9/30/09 7:01 AM | # - re

Hi,

I am VERY GLAD I found this application ! I always liked those raise speed/pitch options (I mean being able to listen to the male version of popular girl singers is hilarious ! haha) + the quality of the sound is a lot better when changing pitch or speed only compared to many software plugins or other softwares similar to this one.

The option of saving the results into a Wav file is AMAZING ! Maybe it's just a little feature, but it makes a whole lot difference =).

THUMBS UP ALL THE WAY ! =)

Hi!

I really like your program; I just finished an article for the german ubuntuusers-wiki (see wiki.ubuntuusers.de/Baustelle/PlayItSlowly ). Perhaps you could have a look at it and tell me if it's ok for you?

I've noticed one minor "bug": The wave-files produced as output are not properly recognised by kd3 and other cd burning applications - any ideas why?

Otherwise: thumps up! ;-)

Comment by Jaron — 1/16/10 9:00 PM | # - re

Nice useful program! I've been looking for something like this. For the next update, it would be nice if there were scroll controls on either end of the sliders to bump them just a bit. If there were buttons on to hit to set the start and end positions it might be a bit easier to set up a loop section, If tuning was in cents (1/100 of a semitone) that would match the readout of many tuners- but that's not essential. I'm using it to learn celtic tunes for a slow session I attend- playing 1-key flute or fiddle.

How to Change the Playback Pitch range: Find the app.py file that gets executed when you launch playitslowly. On my Debian system, it's at /usr/share/python-support/playitslowly/playitslowly/app.py. Should be similar on Ubuntu. No idea about Windows, sorry. Edit this file as root. Find this line: self.pitchchooser = mygtk.HScale(gtk.Adjustment(0.0, -24.0, 24.0, 1.0, 1.0, 0.0)). Copy this line and paste just below. Comment the original line by putting a # in front. Now, change the parameters in your new line of code. I wanted a narrower range with more fine control so I went with (0.0, -2.0, 2.0, 0.05, 0.05, 0.0). Experiment. The 2nd and 3rd parameters control the range, the 4th and 5th control the fine adjustment. Save the file and run playitslowly as usual.

Is it possible to control playitslowly with midi commands ? Like with a midi / OSC pedal ... ?

Comment by jcn — 4/13/10 2:25 AM | # - re

PlayItSlowly doesn't support midi right now. It would be possible to do a hack to translate midi events to x11 key events. I might add this to a future version though.

Comment by Jonas Wagner — 4/13/10 9:38 AM | # - re

Comment by Matt — 7/26/10 11:25 AM | # - re

Hello, I have not the usage, but know some scientific colleagues use that kind of software. So congrats for this project. I dislike the GUI because its look and feel could be more standardized (but it's the general poor feeling and experience created by the whole set, not this one specifically.

remove buttons at bottom and use a toolbar with icons (e.g. like Rhythmbox).
use a menu (open, recent files, save, quit, help, about...). That also facilitates the integration with a translation menu addition (i.e. Ubuntu)
translated GUI probably need a little bit more space.
the unit could be displayed using a gray color (so that it does not overload the text information).
align vertically the "opened file" menu and the "recent" button with the elements below. -> add a function to save parameter profiles to reuse them to same or similar recordings.
Regards.
Good luck.

Fantastic little program. I use it a lot to transcribe audio files. As a suggestion it would be great to have the ability to start and stop the audio with hot keys. While typing the text in LibreOffice to press a key combination to start and stop playback in Playitslowly if possible. If that was possible the next great little option would be to have a key press that would rewind the audio back a preset number of seconds, day 1 or 2 seconds.

You have done a fantastic job though and I hope that you continue with the project.

Comment by Jonas Wagner — 5/9/11 3:12 PM | # - re
- Hi Jonas,
  As I understood it, Neil was asking for a way to control playitslowly while working in another program, without having to switch focus back to playitslowly. I would love that feature as well, it would really help my workflow.
  I use a program called ReMoot to give me universal control of all my other audio playback software on my system. It would be cool if playitslowly can receive play / pause / rewind messages so I could tie it in to ReMoot, or even just make shortcuts on Gnome keyboard manager. The readme shows that it supports some commandline arguments, but I assume that's not a full list? Does playitslowly support receiving any form of messages or any remote access?
  Can you shed any light on all this? :)

  - it currently only supports key events. I'll check if there is a reasonable way to make them global. Implementing DBUS support is probably quite easy too - just didn't have the need for it so far. For me the nicest feature in that direction would be to be able to hook it up to jacks playback handling. Anyway I'll see what I can do.
    Cheers,
    Jonas

  - exactly. I suggested that feature a while ago. Hopefully one of those days Jonas (or somebody else) will find a time to implements it.

Can playitslowly change pitch/speed on a playing CD? or is this an improvement you'd consider making? Really valuable if you could--though the program is terrific already!

I keep comparing your program to Roni Music's "Amazing Slow-Downer," a similar technology for the Windoze world. I use it teaching guitar students--it helps when the student wants to play something blisteringly fast to slow it down to 'space-normal' speed. Also helps to adjust the alarming variations in pitch of some recordings, particularly older rock--otherwise we'd have to keep retuning. Your program has ASD beat in that it has the ability to export an 'altered' file. But often the student has the CD in his hand, and ASD can alter a playing audio CD for me too. PLEASE HELP GET ME OUT OF WINDOZE! ;-)

It would be awesome if there was a Windows Version.

Yeah, count me in as one user who needs the program to control CDs as well--I haven't installed Play It Slowly yet because it's as deal-breaker without it.

Jonas,

Very nice work. This is really catching on big in my guitar class. A lot of people are using OSX. Any change this can be ported over to a Mac?

Thanks man! It was the program that was looking to study music. Great job!

Hi, I would like to use play it slowly on windows, is it possible ?

Comment by Laurence — 9/2/11 7:58 PM | # - re

1.4.0 source download points to 1.3.1, not to 1.4.0

1.3.1 works great :)

Ouch, fixed that.

Sweet little application! It ran just fine on Debian Squeeze. The live tempo change that doesn't pitch shift at the same time is exactly what I needed for the musical rehearsals. The singers stay on key and the dancers get to practice a bit slower.

Just used the tool on umuntu 11.10. Works fine. Really helpfull tool.

One question: If I go with the speed below 0.75 I get artefacts like an echo. Can I get rid of this?

Sadly no, it's a side effect of the algorithm used to slow it down.

Comment by Jonas Wagner — 10/18/11 9:44 PM | # - re

Please release a windows version! ASD is too expensive for me, this is perfect but its not for windows.:(

Comment by PPW — 10/17/11 12:08 PM | # - re

Decided not to doo it because of license/patent issues.

Hi, I'm also interested in the program but am unfortunately using Windows 7. Is there a Windows version yet?

Many thanks!

Julianne

Works fine on Ubuntu 11.10 64-bit
Thanks, very useful, Neil

have you done anything with windows yet? I am a bit of a programmer, primarily database, but do have quite a bit of experience with Python in Windows. Don't mind testing if you want to port.

Hi, and thanks for a brilliant piece of software. I used it frequently with Ubuntu.

A suggestion: When the gstreamer stuff is missing, the program could say something instead of just not working? Got a bit frustrated for a while there. Works now, keep up the good work!

Comment by Jari — 12/4/11 6:41 PM | # - re

Just installed under Ubuntu 10.04 and works perfectly: great software, thanks so much Jonas. Andrea

Comment by Andrea — 12/8/11 6:24 PM | # - re

Nice job ! I use it for a while, and i'm actually coding for midi support with mididings : left to do is saving midi preferences, and support for two simultaneous midi devices (for example keyboard and foot pedal)

Hi Jonas,

I was sat in front of my Ubuntu box last night trying to learn the solos to Iron Man and Seasons in the Abyss on my guitar. I decided to do a quick search to see if there was any software whch would make looping the parts easier. I soon found your app and within a few minutes I was up and running. I couldn't believe how easy it was to grab a section, slow it down and loop it until I nailed it!

I love the simplicity and elegance of the application.

Thanks a lot for the effort you put into this. Thanks to you I know another black Sabbath solo. If only you could help me play as fast as Slayer!

does it work under lubuntu? it worked great with ubuntu but after switching to lubuntu i'm having troubles.

Great software!

Comment by Agakonna — 3/12/12 6:42 PM | # - re

Thanks for the great program!

One feature I wish it had is EQ. It would be great if you could mess with the EQ to hear a section better. For instance, sometimes it's difficult to hear the bass on old recordings which makes it tough to get the correct chord changes. EQ would really help that!

Thanks
