Have been unable to create a WAV file with the following export specs: PCM, 8bit, Mono, 8khz. Have read all of the posts on this topic, tried them, none seem to work. Using Windows 7 Ultimate, 64-bit, SP1. Audacity 2.03, downloaded using exe module on 09-13-13. Have recorded a brief voice message using USB headset, mono mode. Must be exported to above specs in order to upload into a medical However, because the files aren’t compressed, the downside is that WAV files can be much bigger than other audio formats – up to 10 times the file size of an MP3. Most users choose to keep their digital music in MP3 or AAC format as they can store more music on their device. MP3 and AAC are also the default formats for many media players. dswpro • 6 yr. ago. Download goldwave. Open your file. Save as .wav format if its not already. On the menu choose enter. 14000. Then .. Enter the new file name, in the "Save as type" drop down choose: Wave (*.wave). In the Attributes drop down choose PCM unsigned 8 bit mono. (This sets the file to 8-bit, and with the 8000 Hz project sample rate, this means you have a 64 kbps bit rate.) Click OK. Name the file and click Save. To save a recording as a WAV file using Audacity 2.1.2: Open Audacity. Find and open the sound file. If the file is stereo, click above Mute/Solo and choose Tracks > Stereo Track to Mono. The confusion started from the thought that since the PCM is 16bit, a sample will always be 4 bytes whether it is Mono or Stereo but I was wrong! A Stereo sample will be 4 bytes when a Mono sample will be 2 bytes so it is stored as [LSB] [MSB] for a sample! Share. Improve this answer. Follow. . It is a web based online text to speech (tts) tool which can convert from text to speech in audio formats like text to mp3, text to wav file. It is also called as text to voice converter or type and speak or text reader service. The audio files can also be downloaded into your system in the formats like .mp3, .wav, .ogg, .caf and .aac. It's pretty simple: ffmpeg -i input.wav -c:a pcm_mulaw output.wav. Check ffmpeg -codecs for a list of supported codecs. An E in the listing means encoding support. Share. Improve this answer.

In order to start your Arduino PCM Audio experiments, just pick a small MP3 audio file of your choice at first, and then convert it into a 16bit PCM 8kHz monoaural MP3 audio file. The far-famed Audacity software will help you to do this conversion at ease (see a sample screen snip below). Music Converter encodes audio and converts audio files between audio file formats that include FLAC, MP3, xHE-AAC™, AAC, HE-AAC (v2), M4A, WAV, DSD, Opus, Vorbis, Apple Lossless and many more. Batch convert unlimited number of audio files in one go with automatic transfer of all metadata tags. Edit metadata of existing audio files. 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").
