6. I have G729 encoded audio files. I need to programmatically convert them to WAV PCM (16bit 8kHz mono) in the flow of a tool that is doing other thing too. I have an executable that will do that for me. But spawning that external process every time I convert is too heavy on resources. Especially if I need many of them being done in parallel. I need to convert an mp3 file to CCITT u-Law (G711a), 8kHz, 8 bit, mono, or PCM, 8kHz, 16 bit, mono. When i tried it my self, the voice had a lisp. Can anyone help? Audio Services Project ID: #5028292. About the project An example of a 1-stage stream format conversion is the conversion of a PCM format to another PCM format (e.g., 8kHz 16-bit Stereo PCM [SPSF_8kHz16BitStereo] -> 44kHz 8-bit Mono [SPSF_44kHz8BitMono]). This requires only one codec (e.g., "Microsoft PCM Converter"). Step 4: Export the file from Audacity. Use the Export Audio dialog to export your custom ringtone or IVR message to various formats. You can export to 16-bit PCM WAV by choosing "WAV (Microsoft) 16-bit PCM" in that dialog. You can export to the smaller-sized MP3 format by choosing "MP3 Files" in the Export Audio dialog. So let us stay with uncompressed "wave" format. There are two choices you need to make here: sample rate. bit depth. In video we use 48kHz as sample rate, on CD-s it is 44.1 kHz. Both work equally well as far as normal sound goes. Rarely anything different, and then the receiver of the files probably will tell you. 64-bit doubles RAW (.raw, .dbl) Import and Export. Header not included on save. 8-bit signed SAM (.sam) Import and Export. Save as 22050 Hz, Mono 8-bit only. ACM waveform (.wav) Import and Export. Includes multiple formats supported by Microsoft's Audio Compression Manager; files must be converted to a supported ACM codec format before export. ffmpeg creates either WAVE_FORMAT_PCM or WAVE_FORMAT_EXTENSIBLE depending on the "spec" of the input audio. Essentially there's no way to tell it which to create. It does create WAVE_FORMAT_PCM for 16-bit 44.1KHz mono/stereo input, but with modern ffmpeg (3.2 or later), it also checks the channel layout (that is either supplied by the input Click Drop or upload file. Select the WAV file you want to convert to PCM. Click Convert. The audio will be extracted from the video now. Click DOWNLOAD NOW. Or you can type in an email address and click the message icon. The email address will receive a download link. Note: All files are deleted from our servers after 24 hours. WAV 16-bit PCM is eminently suitable whenever you want to burn your exported file to an audio CD. WAV (Microsoft) signed 24-bit PCM No options for this format: 24-bit PCM gives higher quality than 16-bit PCM, but takes up more space. WAV (Microsoft) 32-bit float No options for this format: 32-bit float WAV is a lossless format, a maximum FPS2fG.
