ruby-audio wraps around libsndfile to provide simplified sound reading and writing support to ruby programs

ruby-audio's Issues

require': libsndfile.so.1: cannot open shared object file

I can use ruby-audio perfectly fine on my dev machine (mac os x lion). However, on amazon ec2 (rhel), after bundle installing the gem successfully, I get the following error when trying to start my app:

/usr/local/rvm/gems/ruby-1.9.3-p194/gems/ruby-audio-1.6.1/lib/ruby-audio.rb:6:in require': libsndfile.so.1: cannot open shared object file: No such file or directory - /usr/local/rvm/gems/ruby-1.9.3-p194/gems/ruby-audio-1.6.1/lib/rubyaudio_ext.so (LoadError) from /usr/local/rvm/gems/ruby-1.9.3-p194/gems/ruby-audio-1.6.1/lib/ruby-audio.rb:6:inrescue in <top (required)>'

Any ideas what could be the cause for this?

Thanks.

Only in Memory?

Hi

Is it possible to use your lib to work on memory data ? like a wav file that it is stored in a database...

It's working if I stored the file from database to a tempory file, making the conversation of the tempory to an other temporary, and put the new content in the database ...

Regards
Vincent

Incorrect number of channels in write

I used the following code to copy a 'wav' file:

#!/usr/local/bin/ruby 
require 'rubygems'
require 'ruby-audio'
require 'pp'

snd1 = RubyAudio::Sound.open('/Users/wms5f/data/m1f1.wav')
snd2 = RubyAudio::Sound.open("/Users/wms5f/data/m1f1_2.wav", 'w', snd1.info.clone)
# Create wav output file
buf = RubyAudio::Buffer.double(1000)
puts snd2.info.samplerate
puts snd2.info.format
puts snd2.info.channels
read = snd1.read(buf)
puts snd1.info.samplerate
puts snd1.info.format
puts snd1.info.channels
while read != 0
  puts snd1.info.channels
  puts snd2.info.channels
  snd2.write(buf)
  read = snd1.read(buf)
end
snd1.close
snd2.close

The output was as follows:

8000
65553
2
8000
65553
2
2
2
RubyAudio::Error: channel count mismatch: 1 vs 2

method write    in audioTest3.rb at line 20
method <main>   in audioTest3.rb at line 20

I don't understand how one of the open files could have a setting of 1 channel.

Any thoughts?

Some pointers on how to (cross?) compile this code?

Hi warhammerkid,

I am trying to run the rake gems command, which apparently cross-compiles all the code. I installed MinGW for OS X.

This fails on OS X, because the FLAC headers cannot be found (but are installed on my machine using homebrew) when compiling libsndfile. Here is the first line with an error from tmp/i386-mingw32/ports/libsndfile/1.0.24/compile.log.

    CC     flac.lo
    flac.c:34:33: error: FLAC/stream_decoder.h: No such file or directory

Can you give some pointers how to build this project? Should I just ignore the Rakefile altogether if I want to build it for my own system?

Thanks,
Roel

using gem in vendor

Hi, I´ve copied the gem in the vendor folder for use on heroku, but gets this error message when i try to use it with the waveform gem

Compilation fails with default compiler flags on Ubuntu 13.10 (at least)

On Ubuntu 13.10 (and possibly other systems with the default compiler flag -Werror=format-security) the gem native extension will fail to build. You can get around this by installing with gem install ruby-audio --with-cflags=-Wno-error=format-security but I suppose the C-extension should be updated to not cause a security error (or at least a note added somewhere, I'm not a C expert so not sure what really should be done to remedy).

Compiling fails on Raspbian

I'm trying to compile ruby-audio on a Raspberry Pi running Rasbian, but compilation fails. Here is the error (full log below):

compiling ra_sound.c
ra_sound.c: In function ‘ra_sound_init’:
ra_sound.c:155:5: error: format not a string literal and no format arguments [-Werror=format-security]

Apparently format-security compiler flag is breaking the build. I have tried to compile with -Wno-format-security, but still the build fails with the same error.

Any idea how to fix this?
