I have a phone-recorded conversation that is now evidence in an upcoming Zoom hearing, and I need an experienced audio forensics specialist to determine whether the file is genuine. My primary concern is authenticity—I suspect there may be cut or edited sections and possibly altered voices or other sounds. You will have access to the original phone-recording file (not an MP3/WAV export), along with the surrounding case notes for context. Here’s what I need from you: • A detailed forensic analysis explaining any edits, splices, or voice manipulations you uncover, supported by spectrograms or other clear visual markers. • A concise written report in plain language that I can submit to the court, outlining your methodology, findings, and professional opinion. • Your availability to appear live via Zoom during the hearing to explain those findings and answer any clarification questions from counsel or the judge. The work should follow accepted forensic-audio protocols and be defensible under cross-examination. If you routinely use tools like iZotope RX, Adobe Audition, or forensic suites such as Cedar or Magix Sequoia, please mention that in your response. Once we agree on scope and timeline, I will forward the recording and schedule preferences for the hearing date.

When audio may be used as evidence, the analysis needs to be careful, technical, and clearly documented. I can examine the original recording for potential edits, splices, discontinuities, spectral anomalies, noise-floor changes, and other indicators that may help assess whether the file has been altered. I can also provide waveform and spectrogram analysis with clear documentation of the findings. I’ve completed a related audio clarification project involving detailed analysis and restoration of a WAV recording. You can view the project here: https://www.freelancer.com/projects/audio-services/WAV-Audio-Clarification-Expert-Needed?frm=KarimEmad10&sb=t I work with professional tools such as iZotope RX and Adobe Audition, and I can provide a clear technical report based on the analysis. Send me a message and we can get started right away.

Hi, The key here is not simply improving or listening to the recording - it is determining whether the original file shows defensible signs of editing, splicing, or manipulation and documenting that in a way the court can understand. Here's how I'll approach it: * Examine the original phone-recording file and preserve the source for forensic review. * Analyze waveform, spectrogram, metadata, continuity, noise floor, and encoding behavior. * Look for signs of cuts, splices, inserted audio, or altered voice/sound characteristics. * Document suspicious regions with clear visual markers and timestamps. * Prepare a plain-language report covering methodology, findings, limitations, and professional opinion. * Organize exhibits so the analysis is easy to follow during the Zoom hearing. * Remain available to explain the findings and answer technical questions live. One question before we begin: what is the exact original recording file format and which phone/app created it? Best regards, Christopher
