My very feeble understanding of the .mp3 world is that there are various codecs which enable the reproduction of certain files. What I want to do is use .mp3 files of recorded speech instead of the wav files I'm now using. Since I will only be using my own files and won't have to worry about playing .mp3 files from different sources, can I supply a codec so that it will work on all computers? Is it even necessary to do so? As you can see, these are newbie questions - just trying to get my toes wet before I dive in. -- Brad Blanchard http://www.braser.com Email accepted from the website Back to top alanglloyd@aol.com Guest Posted: Mon Jan 02, 2006 3:31 pm    Post subject: Re: TMediaPlayer, MP3 and Codecs AIUI a limited codec for MP3 files (ie up to 56 Kbits/sec) with a description of "Fraunhofer IIS MPEG Layer-3 Codec (advanced)" is included in a standard XP OS. If you want higher than that I believe one has to get a licence from Frauenhofer for a reputed big bucks. OTOH I have seen an MP3 codec in file I3codecp.exe (initial letter India for I) on the internet which goes higher (to 112 Kbits/sec). Whether this is a pirated codec or a "good enough" hack I don't know. I would have thought 56Kb/s would be good enough for speech. I have writtem programs using GSM for speech quite satisfactorily using MediaPlayer for playback and waveIn???() for recording with playback. Works very well at 11.025KHz 16 bit sampling rate and gives about 2239 bytes/sec for the GSM files. But that's only mono - GSM does not do stereo. Again the GSM codec comes standard with the OS (Win 95, 98 & XP).

Those are the two bits of knowledge I needed to go ahead and plunge in. In short, most if not all people using XP will be able to play such files. Thanks ever so much again, Alan. -- Brad Blanchard http://www.braser.com Email accepted from the website Back to top Nicholas Sherlock Guest Posted: Tue Jan 03, 2006 1:28 am    Post subject: Re: TMediaPlayer, MP3 and Codecs GB Blanchard wrote: Quote: I've just learned that MediaPlayer can play .mp3 files.

Very limited control and it requires a codec to be installed (which it isn't on all operating systems), I'd go for BASS: http://www.un4seen.com/ Or FMOD: http://www.fmod.org/ Cheers, Nicholas Sherlock Back to top alanglloyd@aol.com Guest Posted: Tue Jan 03, 2006 8:19 am    Post subject: Re: TMediaPlayer, MP3 and Codecs You can troll through Sound Recorder to find details of which codecs are install but I have a small app which displays the ACM (Audio Compression Manager) PCM converter and all installed codecs together with details of every format handled. I'll send it to you if you email me. You may also find that TMediaPlayer is somewhat limited in its capability and decide to use waveOut???() & waveIn???() functions. The WaveFormatExEx record for MP3 you will then need is not easily available but I have a copy if you need it.

I'll send it to you if you email me. Thank you for the kind offer, but I think that all I need is either to find out - without doing massive beta-testing - is if most Windows users have a codec already installed which will allow them to hear .mp3 files run through MediPlayer, and if not, to supply one in the program. Nicholas may have solved the second scenario, although the Bass component may be overkill for what I want to do. Quote: You may also find that TMediaPlayer is somewhat limited in its capability and decide to use waveOut???() & waveIn???() functions. The WaveFormatExEx record for MP3 you will then need is not easily available but I have a copy if you need it. In this particular program, the user is trying to mimic the native speaker (that's the .mp3 file) and the recording is only held in memory so that they can listen on the spot - they have no need of saving the file. Therefore, if I can get the .mp3 playing side working, I'll continue using the .wavin .wavout functions I already have for the recording part. I'm just looking at MediaPlayer as an easy way to play the files. But once again, thank you for offer. -- Brad Blanchard http://www.braser.com Email accepted from the website Back to top GB Blanchard Guest Posted: Tue Jan 03, 2006 4:59 pm    Post subject: Re: TMediaPlayer, MP3 and Codecs Nicholas Sherlock wrote: Quote: Very limited control and it requires a codec to be installed (which it isn't on all operating systems), I'd go for BASS: Is there a way to install the codec without using the component? The reason I ask (and I'm open to suggestions) is that I can normalize the volume and control the general quality of the original .wav files by using, for example, GoldWave. So the only step left would be to convert them to .mp3. This is only for spoken words and short sentences, nothing more. Thanks for the tip about Bass. It appears to be a very complete component. I haven't looked at fmod yet. -- Brad Blanchard http://www.braser.com Email accepted from the website Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         BorlandTalk.com Forum Index -> comp.lang.pascal.delphi.misc All times are GMT Page 1 of 1   Jump to: Select a forum C++ Builder Newsgroups----------------C++ BuilderC++ Builder (ActiveX)C++ Builder (Announcements)C++ Builder (Command Line Tools)C++ Builder DatabasesC++ Builder Databases (ADO)C++ Builder Databases (Desktop)C++ Builder Databases (InterBase Express)C++ Builder Databases (Multi-Tier)C++ Builder Databases (SQL Servers)C++ Builder (Graphics)C++ Builder (IDE)C++ Builder (Internet)C++ Builder (Internet Socket)C++ Builder (Internet Web)C++ Builder (Jobs)C++ Builder (Language)C++ Builder (Language C++)C++ Builder (Compatibility with MFC)C++ Builder (Native API)C++ Builder (Non-Technical)C++ Builder (Students)C++ Builder (Third Party Tools)C++ Builder (Upgrade)C++ Builder (VCL)C++ Builder (VCL Components Usage)C++ Builder (VCL Components Development)C++ Builder (VCL Usage)C++ Builder (WinAPI)C++ Builder Installation Delphi Newsgroups----------------Delphi (General)Delphi ActiveX Controls UsageDelphi ActiveX Controls DevelopmentDelphi As400Delphi DatabasesDelphi Databases (ADO)Delphi Databases (dbExpress)Delphi Databases (Desktop)Delphi Databases (InterBase Express)Delphi Databases (Multi-Tier)Delphi Databases (SQL Servers)Delphi DeploymentDelphi GraphicsDelphi IDEDelphi InternationalizationDelphi InternetDelphi Internet Isapi-WebBrokerDelphi Internet WebSnapDelphi Internet WinsockDelphi JobsDelphi Language BASMDelphi Language ObjectPascalDelphi Model Driven Architecture (General)Delphi Model Driven Architecture (Third Party)Delphi MultimediaDelphi Native APIDelphi Non-TechnicalDelphi ObjectPascalDelphi OLE AutomationDelphi OO designDelphi OpenToolsAPIDelphi Reporting-ChartingDelphi RTLDelphi StudentsDelphi TeamSourceDelphi Thirdparty ToolsDelphi Thirdparty Tools (General)Delphi Thirdparty Tools (IntraWeb)Delphi Thirdparty Tools (RaveReports)Delphi UpgradeDelphi VCLDelphi VCL ComponentsDelphi VCL Components UsingDelphi VCL Components WritingDelphi WebServices SOAPDelphi WinAPIDelphi XMLDelphi Installationcomp.lang.pascal.delphi.components.misccomp.lang.pascal.delphi.components.usagecomp.lang.pascal.delphi.components.writingcomp.lang.pascal.delphi.databasescomp.lang.pascal.delphi.misccomp.sources.delphi JBuilder Newsgroups----------------JBuilderJBuilder AnnouncementsJBuilder Applet IssuesJBuilder As400JBuilder CompilerJBuilder CORBA/RMIJBuilder DatabasesJBuilder DB SwingJBuilder DebuggerJBuilder DeploymentJBuilder DocumentationJBuilder EnterpriseJBuilder HandheldJBuilder IDEJBuilder JavaJBuilder JavaAPIJBuilder Java LanguageJBuilder Java SwingJBuilder Java BeansJBuilder Java Beans UsageJBuilder Java Beans DevelopmentJBuilder JBCLJBuilder JDataStoreJBuilder JobsJBuilder LinuxJBuilder MacintoshJBuilder & MobileSetJBuilder MultiLingual AppsJBuilder Non-TechnicalJBuilder OpenToolsJBuilder Servlets (JSP)JBuilder StudentsJBuilder Team DevelopmentJBuilder Thirdparty ToolsJBuilder UpgradeJBuilder Installation InterBase Newsgroups----------------InterBaseInterBase Bug DiscussionInterBase GeneralInterBase IBConsoleInterBase OpenSourceInterBase ReplicationInterBase SQLInterBase ThirdpartyInterBase Installation Miscellaneous Borland Newsgroups----------------AppCenterAppServerEnteraVisiBroker  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
